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

synchronously

internal

clocks.

XORing of the PWM signal and the port

output latch value is done after the ANDing

of channel 0 and 1.
