C

void RTC_Timer32Compare0Set ( uint32_t compare )

Summary

Set the 32-bit timer period value.

Description

This function sets the 32-bit timer compare value. The counter value will be compared against the compare value and a compare match event will occur when the counter matches the compare value. If the library is configured for interrupt mode and if a event handler function has been set through the RTC_Timer32CallbackRegister() function, the event handling function will be called. When the match occurs, the counter can optionally be reset if clear on compare is enabled to generate periodic interrupt.

Precondition

RTC_Initialize must have been called for the associated RTC instance. The RTC peripheral should have been configured in 32-bit Timer Counter mode.

Parameters

Returns

None.

Example

uint32_t period = 0x00000FFF;
RTC_Initialize();
RTC_Timer32Compare0Set(period);
RTC_Timer32CounterSet(0);
RTC_Timer32Start();
while(!RTC_Timer32Compare0HasMatched());

Remarks

This API is available for devices that have more than one compare register in 32-bit mode.
