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 because it takes one
counter/timer clock interval for the initiated event to actually occur. See

You must program TC8L and TC8H to

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). Meanwhile, T8 is loaded with
starts counting again. If T8 reaches 0, the timeout status bit (CTR0, D5) is set, and an

not recommended.
