These registers show condition flags that correspond to GPT events. If the corre-
sponding interrupt enable bit in TMSK1/TMSK2 is set, an interrupt occurs.
When I4/O5 in PACTL is zero, this flag is set each time TCNT matches the TOC5 val-
ue in TI4/O5. When I4/O5 in PACTL is one, the flag is set each time a selected edge
is detected at the I4/O5 pin.
An output compare flag is set each time TCNT matches the corresponding TOC reg-
ister. OCF[4:1] correspond to OC[4:1].
A flag is set each time a selected edge is detected at the corresponding input capture
pin. ICF[3:1] correspond to IC[3:1].
This flag is set each time TCNT advances from a value of $FFFF to $0000.
This flag is set each time the pulse accumulator counter advances from a value of $FF
to $00.
In event counting mode, this flag is set when an active edge is detected on the PAI pin.
In gated time accumulation mode, it is set at the end of the timed period.
Setting a bit in CFORC causes a specific output on OC or PWM pins. PWMC sets
PWM operating conditions.
