Prototype:
void
ROM_TimerPrescaleSet(uint32_t ui32Base,
uint32_t ui32Timer,
uint32_t ui32Value)
ROM Location:
ROM_APITABLE
is an array of pointers located at
0x0100.0010
.
ROM_TIMERTABLE
is an array of pointers located at
ROM_APITABLE[11]
.
ROM_TimerPrescaleSet
is a function pointer located at
ROM_TIMERTABLE[10]
.
Parameters:
ui32Base is the base address of the timer module.
ui32Timer specifies the timer(s) to adjust; must be one of TIMER_A , TIMER_B , or
TIMER_BOTH .
ui32Value
is the timer prescale value which must be between 0 and 255 (inclusive) for 16/32-

is an array of pointers located at
ROM_APITABLE[11]
.
ROM_TimerRTCDisable
is a function pointer located at
ROM_TIMERTABLE[9]
.
Parameters:
ui32Base is the base address of the timer module.
Description:
This function causes the timer to stop counting when in RTC mode.
