R_MTU_CreateChannel

4.2.7 Multi Function Timer

Remarks (2/2) • A callback function is executed by the interrupt processing function. This means that no other interrupt

can be processed until the callback function has completed.

• If the requested period is not a multiple of the minimum period, the actual time period will be more than

the requested time period.

Program example

/* PDL definitions */

#include “r_pdl_cmt.h”

/* PDL device-specific definitions */

#include “r_pdl_definitions.h”

/* Configure CMT channel 0 for 10µs operation */

R_CMT_Create(

);

/* Configure CMT channel 1 for 1KHz operation */

R_CMT_Create(

/* Configure CMT channel 2 using register values */
