Detailed Description

Advanced 16-bit timer with precision PWM support and capture/compare capabilities.

---

Module Operation

---

TimerA is a 16-bit timer/counter with multiple capture/compare registers. TimerA can support multiple capture/compares, PWM outputs, and interval timing. TimerA also has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers.

This peripheral API handles Timer A hardware peripheral.

TimerA features include:

• Asynchronous 16-bit timer/counter with four operating modes
• Selectable and configurable clock source
• Up to seven configurable capture/compare registers
• Configurable outputs with pulse width modulation (PWM) capability
• Asynchronous input and output latching
• Interrupt vector register for fast decoding of all Timer interrupts

---

Basic Operation Modes

---

TimerA can operate in 3 modes:

• Continuous Mode
• Up Mode
• Down Mode

TimerA Interrupts may be generated on counter overflow conditions and during capture compare events.

The TimerA may also be used to generate PWM outputs. PWM outputs can be generated by initializing the compare mode with TimerA_initCompare() and the necessary parameters. The PWM may be customized by selecting a desired timer mode (continuous/up/upDown), duty cycle, output mode, timer period etc. The library also provides a simpler way to generate PWM using TimerA_generatePWM() API. However the level of customization and the kinds of PWM generated are limited in this API. Depending on how complex the PWM is and what level of customization is required, the user can use TimerA_generatePWM() or a combination of TimerA_initCompare and timer start APIs.

The TimerA API provides a set of functions for dealing with the TimerA module. Functions are provided to configure and control the timer, along with functions to modify timer/counter values, and to manage interrupt handling for the timer.

Control is also provided over interrupt sources and events. Interrupts can be generated to indicate that an event has been captured.

---

Programming Example

---

The DriverLib package contains a variety of different code examples that demonstrate the usage of the TimerA module. These code examples are accessible under the examples/ folder of the SDK release as well as through TI Resource Explorer if using Code Composer Studio. These code examples provide a comprehensive list of use cases as well as practical applications involving each module.

Below is a very brief code example showing how to generate a PWM signal using the TimerA DriverLib module.

Below is the configuration parameter for the TimerA PWM config API:

The next snippet of code is used to actually configure the PWM signal:

uint16_t Timer_A_getCounterValue

(

uint32_t

timer

)

Returns the current value of the specified timer. Note that according to the Timer A user guide, reading the value of the counter is unreliable if the system clock is asynchronous from the timer clock. The API addresses this concern by reading the timer count register twice and then determining the integrity of the value. If the two values are within 10 timer counts of each other, the value is deemed safe and returned. If not, the process is repeated until a reliable timer value is determined.

Parameters

timer

is the instance of the Timer_A module. Valid parameters vary from part to part, but can include: TIMER_A0_BASE TIMER_A1_BASE TIMER_A2_BASE TIMER_A3_BASE

Returns

uint32_t Timer_A_getEnabledInterruptStatus

(

uint32_t

timer

)

Get timer interrupt status masked with the enabled interrupts. This function is useful to call in ISRs to get a list of pending interrupts that are actually enabled and could have caused the ISR.

Parameters

timer

is the instance of the Timer_A module. Valid parameters vary from part to part, but can include: TIMER_A0_BASE TIMER_A1_BASE TIMER_A2_BASE TIMER_A3_BASE

Returns

uint32_t. Return interrupt status. Valid values are

• TIMER_A_INTERRUPT_PENDING
• TIMER_A_INTERRUPT_NOT_PENDING

Parameters

timer	is the instance of the Timer_A module. Valid parameters vary from part to part, but can include: TIMER_A0_BASE TIMER_A1_BASE TIMER_A2_BASE TIMER_A3_BASE

	)

Disable capture compare interrupt

Parameters

uint32_t Timer_A_getCaptureCompareInterruptStatus	(	uint32_t	timer,
		uint_fast16_t	captureCompareRegister,
		uint_fast16_t	mask
	)

Parameters

timer	is the instance of the Timer_A module. Valid parameters vary from part to part, but can include: TIMER_A0_BASE TIMER_A1_BASE TIMER_A2_BASE TIMER_A3_BASE
captureCompareRegister	is the selected capture compare register
mask	is the mask for the interrupt status Mask value is the logical OR of any of the following: TIMER_A_CAPTURE_OVERFLOW TIMER_A_CAPTURECOMPARE_INTERRUPT_FLAG

Returns

uint32_t. The mask of the set flags. Valid values is an OR of

• TIMER_A_CAPTURE_OVERFLOW,
• TIMER_A_CAPTURECOMPARE_INTERRUPT_FLAG

uint32_t Timer_A_getCaptureCompareEnabledInterruptStatus	(	uint32_t	timer,
		uint_fast16_t	captureCompareRegister
	)

Return capture compare interrupt status masked with the enabled interrupts. This function is useful to call in ISRs to get a list of pending interrupts that are actually enabled and could have caused the ISR.

Parameters

timer	is the instance of the Timer_A module. Valid parameters vary from part to part, but can include: TIMER_A0_BASE TIMER_A1_BASE TIMER_A2_BASE TIMER_A3_BASE
captureCompareRegister	is the selected capture compare register

Returns

uint32_t. The mask of the set flags. Valid values is an OR of

• TIMER_A_CAPTURE_OVERFLOW,
• TIMER_A_CAPTURECOMPARE_INTERRUPT_FLAG

void Timer_A_registerInterrupt	(	uint32_t	timer,
		uint_fast8_t	interruptSelect,
		void(*)(void)	intHandler
	)

Registers an interrupt handler for the timer capture compare interrupt.

Parameters

timer	is the instance of the Timer_A module. Valid parameters vary from part to part, but can include: TIMER_A0_BASE TIMER_A1_BASE TIMER_A2_BASE TIMER_A3_BASE
interruptSelect	Selects which timer interrupt handler to register. For the timer module, there are two separate interrupt handlers that can be registered: TIMER_A_CCR0_INTERRUPT Corresponds to the interrupt for CCR0 TIMER_A_CCRX_AND_OVERFLOW_INTERRUPT Corresponds to the interrupt for CCR1-6, as well as the overflow interrupt.
intHandler	is a pointer to the function to be called when the timer capture compare interrupt occurs.

This function registers the handler to be called when a timer interrupt occurs. This function enables the global interrupt in the interrupt controller; specific Timer_Ainterrupts must be enabled via Timer_A_enableInterrupt(). It is the interrupt handler's responsibility to clear the interrupt source via Timer_A_clearCaptureCompareInterrupt().

Returns

None.

void Timer_A_unregisterInterrupt	(	uint32_t	timer,
		uint_fast8_t	interruptSelect
	)

Unregisters the interrupt handler for the timer

Parameters

timer	is the instance of the Timer_A module. Valid parameters vary from part to part, but can include: TIMER_A0_BASE TIMER_A1_BASE TIMER_A2_BASE TIMER_A3_BASE
interruptSelect	Selects which timer interrupt handler to register. For the timer module, there are two separate interrupt handlers that can be registered: TIMER_A_CCR0_INTERRUPT Corresponds to the interrupt for CCR0 TIMER_A_CCRX_AND_OVERFLOW_INTERRUPT Corresponds to the interrupt for CCR1-6, as well as the overflow interrupt.

This function unregisters the handler to be called when timer interrupt occurs. This function also masks off the interrupt in the interrupt controller so that the interrupt handler no longer is called.

Returns

None.
