MOTOROLA
The PWM unit has two operational modes. Fast mode uses a clocking rate equal to
1/256 of the prescaler output rate; slow mode uses a rate equal to 1/32768 of the pres-
caler output rate. The duty cycle ratios of the two PWM channels can be individually
controlled by software. The PWMA pin can also output the clock that drives the PWM
counter. PWM pins can also be used as output pins.
