S2LPTimerComputeRxTimerRegValues()

void S2LPTimerComputeRxTimerRegValues	(	uint32_t	lDesiredUsec,
		uint8_t *	pcCounter,
		uint8_t *	pcPrescaler
	)

Parameters

lDesiredUsec	desired rx_timeout in microsecs. This parameter must be a float. Since the counter and prescaler are 8 bit registers the maximum reachable value is maxTime = fTclk x 255 x 255.
pcCounter	pointer to the variable in which the value for the rx_timeout counter has to be stored. This parameter must be a uint8_t*.
pcPrescaler	pointer to the variable in which the value for the rx_timeout prescaler has to be stored. This parameter must be an uint8_t*.

Return values

None

S2LPTimerComputeRxTimerValues()

void S2LPTimerComputeRxTimerValues	(	uint32_t *	pulDesiredUsec,
		uint8_t	cCounter,
		uint8_t	cPrescaler
	)

Parameters

pulDesiredUsec	pointer to rx_timeout in microsecs. Since the counter and prescaler are 8 bit registers the maximum reachable value is maxTime = fTclk x 255 x 255.
cCounter	counter for the rx_timeout. This parameter must be a uint8_t.
cPrescaler	prescaler for the rx_timeout. This parameter must be an uint8_t.

Return values

None

S2LPTimerComputeWakeupTimerRegValues()

void S2LPTimerComputeWakeupTimerRegValues	(	uint32_t	lDesiredUsec,
		uint8_t *	pcCounter,
		uint8_t *	pcPrescaler,
		uint8_t *	pcMulti
	)

Parameters

lDesiredUsec	desired wakeup timeout in microseconds. Since the counter and prescaler are 8 bit registers the maximum reachable value is maxTime = fTclk x 256 x 256.
pcCounter	pointer to the variable in which the value for the wakeup timer counter has to be stored. This parameter must be a uint8_t*.
pcPrescaler	pointer to the variable in which the value for the wakeup timer prescaler has to be stored. This parameter must be an uint8_t*.
