T8_OUT
“Counter Enable” Command,
T8_OUT Switches To Its
Initial Value (CTR1 D1)
Note:
Note:
You can modify the values in TC8H or TC8L at any time. The new values take
effect when they are loaded. Do not write these registers at the time the values
are to be loaded into the counter/timer, to ensure known operation. An initial count
of 1 is not allowed (a nonfunction occurs). An initial count of 0 causes TC8 to
count from 0 to FFh to FEh.
Transition from 0 to FFh is not a time-out condition.
“h” is used for hexadecimal values.
Do not use the same instructions for stopping the counter/
timers and setting the status bits. Two successive commands
are necessary. First, stop the counter/timers, and, second,
reset the status bits. This is required because it takes one
counter/timer clock interval for the initiated event to actually
occur.
