OCxCON2: OUTPUT COMPARE x CONTROL REGISTER 2 (CONTINUED)

Note 1:

Do not use the OCx module as its own synchronization or trigger source.

When the OCy module is turned off, it sends a trigger out signal. If the OCx module uses the OCy module

as a trigger source, the OCy module must be unselected as a trigger source prior to disabling it.

For each OCMPx instance, a different PTG trigger out is used:

OCMP1 – PTG trigger out [0]

OCMP2 – PTG trigger out [1]

OCMP3 – PTG trigger out [2]

OCMP4 – PTG trigger out [3]
