PIC16F/LF1946/47

22.3.7 OPERATION IN SLEEP MODE

In Sleep mode, the TMRx register will not increment

and the state of the module will not change. If the CCPx

pin is driving a value, it will continue to drive that value.

When the device wakes up, TMRx will continue from its

previous state.

22.3.8 CHANGES IN SYSTEM CLOCK

FREQUENCY

The PWM frequency is derived from the system clock

frequency. Any changes in the system clock frequency

will result in changes to the PWM frequency. See

Section 5.0 âOscillator Module (With Fail-Safe

Clock Monitor)â for additional details.

22.3.9 EFFECTS OF RESET

Any Reset will force all ports to Input mode and the

CCP registers to their Reset states.
