Register Map
Table 16-1 on page 406 lists the PWM registers. The offset listed is a hexadecimal increment to the
register’s address, relative to the PWM base address of 0x4002.8000.
■
Set the pulse width of the PWM1 pin for a 75% duty cycle.
■
Start the timers in PWM generator 0.
■
Enable PWM outputs.
■
