ROM_TIMERTABLE is an array of pointers located at ROM_APITABLE[11].
ROM_TimerPrescaleMatchGet is a function pointer located at ROM_TIMERTABLE[13].
Parameters:
ui32Base is the base address of the timer module.
ui32Timer specifies the timer; must be one of TIMER_A or TIMER_B.
Description:
This function gets the value of the input clock prescaler match value. When in a half-width
mode that uses the counter match and prescaler, the prescale match effectively extends the
