11.2.1.3 - Burst Mode
Burst mode is selected by setting bit PB01 in reg-
ister XPWMCON1 to ‘1’. This mode combines the
signals from XPWM channels 0 and 1 onto the
port pin of channel 0. The output of channel 0 is
replaced with the logical AND of channels 0 and 1.
The output of channel 1 can still be used at its
associated output pin (if enabled).
Each of the two channels can either operate in
mode 0 or 1.
Note: It is guaranteed by design, that no
spurious spikes will occur at the output pin
of channel 0 in this mode. The output of
the AND gate will be transferred to the
output pin synchronously to internal
clocks.
XORing of the PWM signal and the port
output latch value is done after the ANDing
of channel 0 and 1.
