C
bool RTC_Timer16Compare0HasMatched(void)
Summary
Returns true if the 16-bit Timer Compare 0 value has matched the counter.
Description
This function returns true if the 16-bit Timer Compare 0 value has matched the counter. When operating in 16-bit Timer Counter mode, the RTC peripheral compares the counter value with two defined compare values (Compare 0 and Compare 1). This function will return true if the counter value has matched the Compare 0 value and also resets the hardware status flags if when match has occurred.
The Compare 0 Value could have been configured via MHC or at run time by calling the RTC_Timer16Compare0Set() function. The RTC_Timer16Compare0ValueMatched() function allows the application to poll for the compare value match.
Precondition
RTC_Initialize, RTC_Timer16Start must have been called for the associated RTC instance. The RTC value should have been configured for 16-bit Timer Counter Mode. The Generate Compare 0 API option in MHC should have been enabled.
Parameters
None.
Returns
True if counter has matched Compare 0 Value, False otherwise.
Example
RTC_Initialize(); RTC_Timer16CounterSet(0); RTC_Timer16PeriodSet(0xFFF); // Calling the RTC_Timer16Compare0Set() function will override the // Compare 0 value that was set via MHC. RTC_Timer16Compare0Set(0x3F); RTC_Timer16Start(); // Wait till the Compare 0 value has matched. while(!RTC_Timer16Compare0HasMatched());
Remarks
None.
