Example of control word and count value setting
The minimum and maximum count values which can be counted in each mode are listed
below.
Counter #0: Read/Load LSB only, Mode 3, Binaty count, count value 3H
Counter #1: Read/Load MSB only, Mode 5, Binaty count, count value AA00H
Counter #2: Read/Load LSB and MSB, Mode 0, BCD count, count value 1234
MVI A, 1EH
OUT n3
Counter #0 control word setting
MVI A, 6AH
OUT n3
Counter #1 control word setting
MVI A, B1H
OUT n3
Counter #2 control word setting
