PIC12LF1840T48A
24.3.6
OPERATION IN SLEEP MODE
In Sleep mode, the TMR2 register will not increment
and the state of the module will not change. If the CCP1
pin is driving a value, it will continue to drive that value.
When the device wakes up, TMR2 will continue from its
previous state.
24.3.7
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 “Oscillator Module (With Fail-Safe
Clock Monitor)” for additional details.
24.3.8
EFFECTS OF RESET
Any Reset will force all ports to Input mode and the
CCP registers to their Reset states.
24.3.9
ALTERNATE PIN LOCATIONS
This module incorporates I/O pins that can be moved to
other locations with the use of the alternate pin function
register, APFCON. To determine which pins can be
moved and what their default locations are upon a
reset, see Section 12.1 “Alternate Pin Function” for
more information.
