RX62N Group, RX621 Group 5. Usage Examples
For full flexibility, the R_TMR_CreateChannel() function can be used.
In this example, Timer channel 0 is configured to provide pulses on pin TMO0, with a pulse width of 200 ticks of
PCLK and a duty cycle of 50%.
Note that the output transitions and counter clearing occur after the compare match has occurred. So the values
for compare match A and compare match B should be 1 less than the required count.

0 at a compare match B */
