Detailed Description

Introduction

The Input/Output Controller (IOC) controls the functionality of the pins (called DIO). The IOC consists of two APIs:

• MCU IOC API selects which peripheral module is connected to the individual DIO and thus allowed to control it. It also controls individual drive strength, slew rate, pull-up/pull-down, edge detection, etc.
• AON IOC API controls the general drive strength definitions, IO latches, and if the LF clock is routed to a DIO for external use.

For more information on the AON IOC see the AON IOC API.

Note

The output driver of a DIO is not configured by the IOC API (except for drive strength); instead, it is controlled by the peripheral module which is selected to control the DIO.

A DIO is considered "software controlled" if it is configured for GPIO control which allows the System CPU to set the value of the DIO via the GPIO API. Alternatively, a DIO can be "hardware controlled" if it is controlled by other modules than GPIO.

API

The API functions can be grouped like this:

Configure all settings at the same time:

• IOCPortConfigureSet()
• IOCPortConfigureGet()

Configure individual settings:

• IOCIODrvStrengthSet()
• IOCIOHystSet()
• IOCIOInputSet()
• IOCIOIntSet()
• IOCIOModeSet()
• IOCIOPortIdSet()
• IOCIOPortPullSet()
• IOCIOShutdownSet()
• IOCIOSlewCtrlSet()

Handle edge detection events:

• IOCIntEnable()
• IOCIntDisable()
• IOCIntClear()
• IOCIntStatus()
• IOCIntRegister()
• IOCIntUnregister()

Configure IOCs for typical use cases (can also be used as example code):

• IOCPinTypeAux()
• IOCPinTypeGpioInput()
• IOCPinTypeGpioOutput()
• IOCPinTypeI2c()
• IOCPinTypeSsiMaster()
• IOCPinTypeSsiSlave()
• IOCPinTypeUart()

Function Documentation

static void IOCIntClear ( uint32_t  ui32IOId )

inlinestatic

Clears the IO edge interrupt source.

The specified IO edge interrupt source is cleared, so that it no longer asserts. This function must be called in the interrupt handler to keep the interrupt from being recognized again immediately upon exit.

Note

Due to write buffers and synchronizers in the system it may take several clock cycles from a register write clearing an event in a module and until the event is actually cleared in the NVIC of the system CPU. It is recommended to clear the event source early in the interrupt service routine (ISR) to allow the event clear to propagate to the NVIC before returning from the ISR. At the same time, an early event clear allows new events of the same type to be pended instead of ignored if the event is cleared later in the ISR. It is the responsibility of the programmer to make sure that enough time has passed before returning from the ISR to avoid false re-triggering of the cleared event. A simple, although not necessarily optimal, way of clearing an event before returning from the ISR is:

1. Write to clear event (interrupt source). (buffered write)
2. Dummy read from the event source module. (making sure the write has propagated)
3. Wait two system CPU clock cycles (user code or two NOPs). (allowing cleared event to propagate through any synchronizers)

Parameters

ui32IOId

is the IO causing the interrupt. IOID_0 ... IOID_31

Returns

None

{
    // Check the arguments.
    ASSERT(ui32IOId <= IOID_31);

    // Clear the requested interrupt source by clearing the event.
    GPIO_clearEventDio(ui32IOId);
}

Here is the call graph for this function:

void IOCIntDisable

(

uint32_t

ui32IOId

)

Disables individual IO edge interrupt sources.

This function disables the indicated IO edge interrupt source. Only the sources that are enabled can be reflected to the processor interrupt; disabled sources have no effect on the processor.

Parameters

is the IO edge interrupt source to be disabled. IOID_0 ... IOID_31

Returns

None

{
    uint32_t ui32IOReg;

}

void IOCIntEnable

(

uint32_t

ui32IOId

)

Enables individual IO edge detect interrupt.

Returns

None

{
    uint32_t ui32IOReg;
    uint32_t ui32Config;

    // Check the arguments.

    ui32Config |= IOC_IOCFG0_EDGE_IRQ_EN;
    HWREG(ui32IOReg) = ui32Config;
}

static void IOCIntRegister ( void(*)(void)  pfnHandler )

inlinestatic

Register an interrupt handler for an IO edge interrupt in the dynamic interrupt table.

Note

Only use this function if you want to use the dynamic vector table (in SRAM)!

This function registers a function as the interrupt handler for a specific interrupt and enables the corresponding interrupt in the interrupt controller.

Specific IO interrupts must be enabled via IOCIntEnable(). It is the interrupt handler's responsibility to clear the interrupt source.

Parameters

pfnHandler

is a pointer to the function to be called when the IOC interrupt occurs.

Returns

None

See also

IntRegister() for important information about registering interrupt handlers.

{
    // Register the interrupt handler.
    IntRegister(INT_AON_GPIO_EDGE, pfnHandler);

    // Enable the IO edge interrupt.
    IntEnable(INT_AON_GPIO_EDGE);
}

Here is the call graph for this function:

static uint32_t IOCIntStatus ( uint32_t  ui32IOId )

inlinestatic

Returns the status of the IO interrupts.

Parameters

ui32IOId

is the IO to get the status for. IOID_0 ... IOID_31

Returns

None

{
    // Check the arguments.
    ASSERT(ui32IOId <= IOID_31);

    // Get the event status.
    return (GPIO_getEventDio(ui32IOId));
}

Here is the call graph for this function:

static void IOCIntUnregister ( void  )

inlinestatic

Unregisters an interrupt handler for a IO edge interrupt in the dynamic interrupt table.

This function does the actual unregistering of the interrupt handler. It clears the handler to be called when an IO edge interrupt occurs.

Returns

None

See also

IntRegister() for important information about registering interrupt handlers.

{
    // Disable the interrupts.
    IntDisable(INT_AON_GPIO_EDGE);

    // Unregister the interrupt handler.
    IntUnregister(INT_AON_GPIO_EDGE);
}

Here is the call graph for this function:

void IOCIODrvStrengthSet	(	uint32_t	ui32IOId,
		uint32_t	ui32IOCurrent,
		uint32_t	ui32DrvStrength
	)

Configure the drive strength source and current mode of an IO port.

The drive strength of an IO is configured by a combination of multiple settings in several modules. The drive strength source ui32DrvStrength is used for controlling drive strength at different supply levels. When set to AUTO the battery monitor (BATMON) adjusts the drive strength to compensate for changes in supply voltage in order to keep IO current constant. Alternatively, drive strength source can be controlled manually by selecting one of three options each of which is configurable in the AON IOC by AONIOCDriveStrengthSet().

Each drive strength source has three current modes: Low-Current (LC), High-Current (HC), and Extended-Current (EC), and typically drive strength doubles when selecting a higher mode. I.e. EC = 2 x HC = 4 x LC.

Note

Not all IOs support Extended-Current mode. See datasheet for more information on the specific device.

Parameters

ui32IOId	defines the IO to configure. IOID_0 ... IOID_31
ui32IOCurrent	selects the IO current mode. IOC_CURRENT_2MA : Low-Current mode. Min 2 mA when ui32DrvStrength is set to IOC_STRENGTH_AUTO. IOC_CURRENT_4MA : High-Current mode. Min 4 mA when ui32DrvStrength is set to IOC_STRENGTH_AUTO. IOC_CURRENT_8MA : Extended-Current mode. Min 8 mA for double drive strength IOs (min 4 mA for normal IOs) when ui32DrvStrength is set to IOC_STRENGTH_AUTO.
ui32DrvStrength	sets the source for drive strength control of the IO port. IOC_STRENGTH_AUTO : Automatic drive strength based on battery voltage. IOC_STRENGTH_MAX : Maximum drive strength, used for low supply levels. Controlled by AON IOC (see AONIOCDriveStrengthSet()). IOC_STRENGTH_MED : Medium drive strength, used for medium supply levels. Controlled by AON IOC (see AONIOCDriveStrengthSet()). IOC_STRENGTH_MIN : Minimum drive strength, used for high supply levels. Controlled by AON IOC (see AONIOCDriveStrengthSet()).

Returns

None

void IOCPinTypeAux

(

uint32_t

ui32IOId

)

Configure an IO for AUX control.

Use this function to enable AUX to control a specific IO. Please note, that when using AUX to control the IO, the input/output control in the IOC is bypassed and completely controlled by AUX, so enabling or disabling input in the IOC has no effect.

Note

The IOs available for AUX control can vary from device to device.

Parameters

ui32IOId

is the IO to setup for AUX usage. IOID_0 ... IOID_31 IOID_UNUSED

Returns

None
