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. Sec-
ond, 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

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 time-out status bit (CTR0, D5) is set, and an
Using the same instructions for stopping the counter/timers and setting the status bits is
not recommended.
