Function Documentation

static uint64_t TSTMR_ReadTimeStamp ( TSTMR_Type *  base )

inlinestatic

This function reads the low and high registers and returns the 56-bit free running counter value. This can be read by software at any time to determine the software ticks. TSTMR registers can be read with 32-bit accesses only. The TSTMR LOW read should occur first, followed by the TSTMR HIGH read.

Parameters

base	TSTMR peripheral base address.

Returns

The 56-bit time stamp value.

static void TSTMR_DelayUs ( TSTMR_Type *  base, uint32_t  delayInUs  )

inlinestatic

This function repeatedly reads the timestamp register and waits for the user-specified delay value.

Parameters

base	TSTMR peripheral base address.
delayInUs	Delay value in microseconds.
