DESCRIPTION OF OPERATION
MSM82C53-2 functions are selected by a control word from the CPU. In the required program
sequence, the control word setting is followed by the count value setting and execution of the
desired timer operation.
Control Word and Count Value Program
Each counter operation mode is set by control word programming. The control word format
is out-lined below.
