REGISTER 18-3:
18.4.7.1
The auto-shutdown feature can be configured to allow
automatic restarts of the module following a shutdown
event. This is enabled by setting the P1RSEN bit of the
ECCP1DEL register (ECCP1DEL<7>).
In Shutdown mode with P1RSEN = 1 (Figure 18-10),
the ECCP1ASE bit will remain set for as long as the
cause of the shutdown continues. When the shutdown
condition clears, the ECCP1ASE bit is cleared. If
P1RSEN = 0 (Figure 18-11), once a shutdown condi-
tion occurs, the ECCP1ASE bit will remain set until it is
cleared by firmware. Once ECCP1ASE is cleared, the
Enhanced PWM will resume at the beginning of the
next PWM period.
Independent of the P1RSEN bit setting, if the
auto-shutdown source is one of the comparators, the
shutdown condition is a level. The ECCP1ASE bit
cannot be cleared as long as the cause of the shutdown
persists.

The Auto-Shutdown mode can be forced by writing a ‘1’
to the ECCP1ASE bit.
18.4.8
When the ECCP1 module is used in the PWM mode,
the application hardware must use the proper external
pull-up and/or pull-down resistors on the PWM output
pins. When the microcontroller is released from Reset,
all of the I/O pins are in the high-impedance state. The
external circuits must keep the power switch devices in
the OFF state until the microcontroller drives the I/O
pins with the proper signal levels, or activates the PWM
output(s).
The CCP1M<1:0> bits (CCP1CON<1:0>) allow the
user to choose whether the PWM output signals are
active-high or active-low for each pair of PWM output
pins (P1A/P1C and P1B/P1D). The PWM output
polarities must be selected before the PWM pins are
configured as outputs. Changing the polarity configura-
tion while the PWM pins are configured as outputs is
not recommended since it may result in damage to the
application circuits.
