Caution:
T8_OUT
Counter Enable Command;
T8_OUT Switches to Its
Initial Value (CTR1 D1)
Two successive commands are necessary. First, the counter/timers must be stopped.
Second, the status bits must be reset. These commands are required as it takes one counter/
timer clock interval for the initiated event to actually occur. See
T8 DEMODULATION Mode
You must program TC8L and TC8H to
(rising, falling, or both depending on CTR1, D5; D4) is detected, it starts to count down.
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected
during counting, the current value of T8 is complemented and put into one of the capture
registers. If it is a positive edge, data is put into LO8; if it is a negative edge, data is put
into HI8. From that point, one of the edge detect status bits (CTR1, D1; D0) is set, and an
interrupt can be generated if enabled (CTR0, D2).

T8_OUT Switches to Its
Initial Value (CTR1 D1)
Using the same instructions for stopping the counter/timers and setting the status bits is
not recommended.
