Timer
Parameters:
ui32Base is the base address of the timer module.
ui32IntFlags is the bit mask of the interrupt sources to be enabled.
Description:
Enables the indicated timer interrupt sources. Only the sources that are enabled can be re-
flected to the processor interrupt; disabled sources have no effect on the processor.
The ui32IntFlags parameter must be the logical OR of any combination of the following:
TIMER_CAPB_EVENT - Capture B event interrupt
TIMER_CAPB_MATCH - Capture B match interrupt
TIMER_TIMB_TIMEOUT - Timer B timeout interrupt
TIMER_RTC_MATCH - RTC interrupt mask
TIMER_CAPA_EVENT - Capture A event interrupt
TIMER_CAPA_MATCH - Capture A match interrupt
TIMER_TIMA_TIMEOUT - Timer A timeout interrupt
Returns:
None.
21.2.1.12 ROM_TimerIntStatus
Gets the current interrupt status.
Prototype:
uint32_t
ROM_TimerIntStatus(uint32_t ui32Base,
bool bMasked)
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_TimerIntStatus is a function pointer located at ROM_TIMERTABLE[21].
Parameters:
ui32Base is the base address of the timer module.
bMasked is false if the raw interrupt status is required and true if the masked interrupt status
is required.
Description:
This returns the interrupt status for the timer module. Either the raw interrupt status or the
status of interrupts that are allowed to reflect to the processor can be returned.
Returns:
The current interrupt status, enumerated as a bit field of values described in
ROM_TimerIntEnable().
