REGISTERS

PWM_PERIOD

PWM_PERIOD	Address:	1FB4H
	Reset State:	00H

The PWM period (PWM_PERIOD) register controls the period of the PWM outputs. It contains a value that determines the number of state counts necessary for incrementing the PWM counter. The value of PWM_PERIOD is loaded into the PWM period count register whenever the count equals zero.
