T8_OUT
Caution:
Notes:
Counter Enable command;
T8_OUT, switches to its
initial value (CTR1 data bit 1)
1. The “h” suffix denotes hexadecimal values.
2. Transition from 0 to
Using the same instructions for stopping the counter/timers and setting the status bits is not
recommended.
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
