Specify the interrupt priority level (0
–
7) to be set in the interrupt control register.
(H8/300H)
Specify the interrupt priority level (0–1) to be set in the interrupt control register. For
the CPUs that do not have an interrupt control register, specify 0.
[data3]
(M16C)(H8/300H)
Specify 0.
(R8C)
When using timer X, specify the set value for the timer register.
[data4]
(M16C) (H8/300H)
Specify 0.
(R8C)
Specify the set value for the prescaler register.
Return value
If the timer specification is incorrect, RAPI_FALSE is returned; otherwise, RAPI_TRUE
is returned.
Functionality
Timer (pulse width measurement mode)
Reference
__EnablePulseWidthMeasurementMode , __DestroyPulseWidthMeasurementMode ,
__GetPulseWidthMeasurementMode
Remark
•
If an undefined value is specified in the first argument, operation of the API cannot
be guaranteed.
•
The specifiable timers differ with each CPU used.
•
When used for the H8/300H, this API specify when freeing it from module stanby
state.
Program example
#include "rapi_timer_r8c_13.h"
void TimerIntFunc( void ){}
void func( void )
{
/* Set up timer X as pulse width measurement mode */
__CreatePulseWidthMeasurementMode(
RAPI_TIMER_X|RAPI_TIMER_ON|RAPI_RISING_FALLING|RAPI_F8,
5, 0x80, 0x80, TimerIntFunc);
