These registers show condition flags that correspond to various GPT events. If the corresponding inter-
rupt enable bit in TMSK1/TMSK2 is set, an interrupt occurs.
I4/O5F — Input Capture 4/Output Compare 5 Flag
When I4/O5 in PACTL is zero, this flag is set each time TCNT matches the value in TOC5. When I4/O5
in PACTL is one, the flag is set each time a selected edge is detected at the I4/O5 pin.
OCF[4:1] — Output Compare Flags
An output compare flag is set each time TCNT matches the corresponding TOC register. OCF[4:1] cor-
respond to OC[4:1].
ICF[3:1] — Input Capture Flags
A flag is set each time a selected edge is detected at the corresponding input capture pin. ICF[3:1] cor-
respond to IC[3:1].
TOF — Timer Overflow Flag
This flag is set each time TCNT advances from a value of $FFFF to $0000.
PAOVF — Pulse Accumulator Overflow Flag
This flag is set each time the pulse accumulator counter advances from a value of $FF to $00.
PAIF — Pulse Accumulator Flag
In event counting mode, this flag is set when an active edge is detected on the PAI pin. In gated time
accumulation mode, PAIF is set at the end of the timed period.
Setting a bit in CFORC causes a specific output on OC.
FOC[5:1] — Force Output Compare
FOC[5:1] correspond to OC[5:1].
0 = Causes no action on corresponding output compare pin.
1 = Causes pin action programmed for corresponding OC pin, but the OC flag is not set.
The 9-bit prescaler value can be read from bits [8:0] at this address. Bits [15:9] always read as zeros.
Reset state is $0000.
