14.4.8
In Sleep mode, all clock sources are disabled. Timer2
will not increment and the state of the module will not
change. If the ECCP pin is driving a value, it will con-
tinue to drive that value. When the device wakes up, it
will continue from this state. If Two-Speed Start-ups are
enabled, the initial start-up frequency from HFINTOSC
and the postscaler may not be stable immediately.
In PRI_IDLE mode, the primary clock will continue to
clock the ECCP module without change. In all other
power-managed modes, the selected power-managed
mode clock will clock Timer2. Other power-managed
mode clocks will most likely be different than the
primary clock frequency.
14.4.8.1
If the Fail-Safe Clock Monitor is enabled, a clock failure
will force the device into the RC_RUN Power-Managed
mode and the OSCFIF bit of the PIR2 register will be
set. The ECCP will then be clocked from the internal
oscillator clock source, which may have a different
clock frequency than the primary clock.
See the previous section for additional details.
14.4.9
Both Power-on Reset and subsequent Resets will force
all ports to Input mode and the CCP registers to their
Reset states.
This forces the enhanced CCP module to reset to a
state compatible with the standard CCP module.
