10. Multifunction Timer Pulse Unit (MTU)
PWM Mode Operation Examples⎯PWM Mode 1 (Figure 10.24): A TGRA register compare-
match is used as a TCNT counter clear source, the TGRA register initial output value and output
compare output value are both 0, and the TGRB register output compare output value is a 1. In
this example, the value established in the TGRA register becomes the period and the value
established in the TGRB register becomes the duty cycle.
