Mode (M2, M1, M0):

BCD:
Operation count mode setting
After setting Read/Load, Mode and BCD in each counter as outlined above, next set the desired
count value. (In some Modes, the count value is set first. In next clock, loading is performed,
then counting starts.) This count value setting must conform with the Read/Load format set
in advance. Note that the internal counters are reset to 0000H during control word setting. The
counter value (0000H) can’t be read.
The program sequence of the MSM82C54-2 is flexible.
Free sequence programming is possible as long as the two following rules are observed:
(i) Write the control word before writing the initial count value in each counter.
(ii) Write the initial count value according to the count value read/write format specified by the
control word.
Note: Unlike the MSM82C53-2, the MSM82C54-2 allows count value setting for another
counter between LSB and MSB settings.
