15.13 PWM Update Lockout
For a complex PWM application, the user may need to
write up to three Duty Cycle registers and the Time
Base Period register, PTPER, at a given time. In some
applications, it is important that all buffer registers be
written before the new duty cycle and period values are
loaded for use by the module.
The PWM update lockout feature is enabled by setting
the UDIS control bit in the PWMCON2 SFR. The UDIS
bit affects all Duty Cycle Buffer registers and the PWM
Time Base Period buffer, PTPER. No duty cycle
changes or period value changes will have effect while
UDIS = 1.
15.14 PWM Special Event Trigger
The PWM module has a Special Event Trigger that
allows A/D conversions to be synchronized to the PWM
time base. The A/D sampling and conversion time may
be programmed to occur at any point within the PWM
period. The Special Event Trigger allows the user to
minimize the delay between the time when A/D conver-
sion results are acquired and the time when the duty
cycle value is updated.
The PWM Special Event Trigger has an SFR named
SEVTCMP, and five control bits to control its operation.
The PTMR value for which a Special Event Trigger
should occur is loaded into the SEVTCMP register.
When the PWM time base is in a Continuous Up/Down
Count mode, an additional control bit is required to
specify the counting phase for the Special Event Trig-
ger. The count phase is selected using the SEVTDIR
control bit in the SEVTCMP SFR. If the SEVTDIR bit is
cleared, the Special Event Trigger will occur on the
upward counting cycle of the PWM time base. If the
SEVTDIR bit is set, the Special Event Trigger will occur
on the downward count cycle of the PWM time base.
The SEVTDIR control bit has no effect unless the PWM
time base is configured for a Continuous Up/Down
Count mode.

15.14.1
The PWM Special Event Trigger has a postscaler that
allows a 1:1 to 1:16 postscale ratio. The postscaler is
configured by writing the SEVOPS<3:0> control bits in
the PWMCON2 SFR.
The special event output postscaler is cleared on the
following events:
• Any write to the SEVTCMP register
• Any device Reset
15.15 PWM Operation During CPU Sleep
The Fault A input pin has the ability to wake the CPU
from Sleep mode. The PWM module generates an
interrupt if the Fault pin is driven low while in Sleep.
15.16 PWM Operation During CPU Idle
The PTCON SFR contains a PTSIDL control bit. This
bit determines if the PWM module will continue to
operate or stop when the device enters Idle mode. If
PTSIDL = 0, the module will continue to operate. If
PTSIDL = 1, the module will stop operation as long as
the CPU remains in Idle mode.
