15.13 PWM Update Lockout
For a complex PWM application, the user may need to
write up to four 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.
If the IUE bit is set, any change to the Duty Cycle
registers will be immediately updated regardless of the
UDIS bit state. The PWM Period register updates
(PTPER) are not affected by the IUE control bit.
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
conversion 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 an Up/Down Counting
mode, an additional control bit is required to specify the
counting phase for the special event trigger. 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 an Up/Down Counting 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 and Fault B input pins have the ability to
wake the CPU from Sleep mode. The PWM module
generates an interrupt if either of the Fault pins 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.
