The output compare channels have the ability to gener-
ate an interrupt on a compare match, for whichever
Match mode has been selected.
For all modes except the PWM mode, when a compare
event occurs, the respective interrupt flag (OCxIF) is
asserted and an interrupt will be generated, if enabled.
The OCxIF bit is located in the corresponding IFS
STATUS register, and must be cleared in software. The
interrupt is enabled via the respective compare inter-
rupt enable (OCxIE) bit, located in the corresponding
IEC Control register.
For the PWM mode, when an event occurs, the respec-
tive timer interrupt flag (T2IF or T3IF) is asserted and
an interrupt will be generated, if enabled. The IF bit is
located in the IFS0 STATUS register, and must be
cleared in software. The interrupt is enabled via the
respective timer interrupt enable bit (T2IE or T3IE),
located in the IEC0 Control register. The output com-
pare interrupt flag is never set during the PWM mode of
operation.
