Read/Write Access: Unrestricted.
Initialization: 00H on any type of reset
The PWM channel n operating frequency is derived
from the frequency selected by PWnS2–0 (described
above) divided by the value of (PWnFG) + 1. Thus if
(PWnFG) = 0, divisor is 1, (PWnFG) = 1, divisor = 2,
(PWnFG) = 2, divisor = 3, etc. This value is the reload

value for the frequency generator’s 8–bit auto–reload-
able timer. The timer’s sole purpose is to generate the
clocking frequency for PWM n and is not otherwise
accessible. The PWM frequency will be correct after
one reload has occurred.
