Timer
21.2.1.8 ROM_TimerEnable
Enables the timer(s).
Prototype:
void
ROM_TimerEnable(uint32_t ui32Base,
uint32_t ui32Timer)
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_TimerEnable
is a function pointer located at
ROM_TIMERTABLE[1]
.
Parameters:
ui32Base is the base address of the timer module.
ui32Timer specifies the timer(s) to enable; must be one of TIMER_A , TIMER_B , or
TIMER_BOTH .
Description:
This will enable operation of the timer module. The timer must be configured before it is en-
abled.
Returns:
None.
21.2.1.9 ROM_TimerIntClear
Clears timer interrupt sources.
Prototype:
void
ROM_TimerIntClear(uint32_t ui32Base,
uint32_t ui32IntFlags)
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_TimerIntClear
is a function pointer located at
ROM_TIMERTABLE[0]
.
Parameters:
ui32Base is the base address of the timer module.
ui32IntFlags is a bit mask of the interrupt sources to be cleared.
Description:
The specified timer interrupt sources are cleared, so that they no longer assert. This must be
done in the interrupt handler to keep it from being called again immediately upon exit.
The ui32IntFlags parameter has the same definition as the ui32IntFlags parameter to
ROM_TimerIntEnable() .
