Detailed Description

Function Documentation

void WDT_A_hold

(

uint16_t

baseAddress

)

Holds the Watchdog Timer.

This function stops the watchdog timer from running, that way no interrupt or PUC is asserted.

Parameters

baseAddress

is the base address of the WDT_A module.

Returns

None

void WDT_A_initIntervalTimer	(	uint16_t	baseAddress,
		uint8_t	clockSelect,
		uint8_t	clockDivider
	)

Sets the clock source for the Watchdog Timer in timer interval mode.

This function sets the watchdog timer as timer interval mode, which will assert an interrupt without causing a PUC.

Parameters

baseAddress	is the base address of the WDT_A module.
clockSelect	is the clock source that the watchdog timer will use. Valid values are: WDT_A_CLOCKSOURCE_SMCLK [Default] WDT_A_CLOCKSOURCE_ACLK WDT_A_CLOCKSOURCE_VLOCLK WDT_A_CLOCKSOURCE_XCLK Modified bits are WDTSSEL of WDTCTL register.
clockDivider	is the divider of the clock source, in turn setting the watchdog timer interval. Valid values are: WDT_A_CLOCKDIVIDER_2G WDT_A_CLOCKDIVIDER_128M WDT_A_CLOCKDIVIDER_8192K WDT_A_CLOCKDIVIDER_512K WDT_A_CLOCKDIVIDER_32K [Default] WDT_A_CLOCKDIVIDER_8192 WDT_A_CLOCKDIVIDER_512 WDT_A_CLOCKDIVIDER_64 Modified bits are WDTIS and WDTHOLD of WDTCTL register.

Returns

None

void WDT_A_initWatchdogTimer	(	uint16_t	baseAddress,
		uint8_t	clockSelect,
		uint8_t	clockDivider
	)

Sets the clock source for the Watchdog Timer in watchdog mode.

This function sets the watchdog timer in watchdog mode, which will cause a PUC when the timer overflows. When in the mode, a PUC can be avoided with a call to WDT_A_resetTimer() before the timer runs out.

Parameters

baseAddress	is the base address of the WDT_A module.
clockSelect	is the clock source that the watchdog timer will use. Valid values are: WDT_A_CLOCKSOURCE_SMCLK [Default] WDT_A_CLOCKSOURCE_ACLK WDT_A_CLOCKSOURCE_VLOCLK WDT_A_CLOCKSOURCE_XCLK Modified bits are WDTSSEL of WDTCTL register.
clockDivider	is the divider of the clock source, in turn setting the watchdog timer interval. Valid values are: WDT_A_CLOCKDIVIDER_2G WDT_A_CLOCKDIVIDER_128M WDT_A_CLOCKDIVIDER_8192K WDT_A_CLOCKDIVIDER_512K WDT_A_CLOCKDIVIDER_32K [Default] WDT_A_CLOCKDIVIDER_8192 WDT_A_CLOCKDIVIDER_512 WDT_A_CLOCKDIVIDER_64 Modified bits are WDTIS and WDTHOLD of WDTCTL register.

Returns

None

void WDT_A_resetTimer

(

uint16_t

baseAddress

)

Resets the timer counter of the Watchdog Timer.

This function resets the watchdog timer to 0x0000h.

Parameters

baseAddress

is the base address of the WDT_A module.

Returns

None

void WDT_A_start

(

uint16_t

baseAddress

)

Starts the Watchdog Timer.

This function starts the watchdog timer functionality to start counting again.

Parameters

baseAddress

is the base address of the WDT_A module.

Returns

None
