Detailed Description

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)

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 AUTO. IOC_CURRENT_4MA : High-Current mode. Min 4 mA when ui32DrvStrength is set to 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 AUTO.
ui32DrvStrength	sets the source for drive strength control of the IO port. IOC_STRENGTH_AUTO : Automatic drive strength, controlled by AON BATMON based on battery voltage (default). 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()).
