•
Specify 3 of SW3 and 0 and 1 of SW4 to reset the values of DM1900 to DM1999, counter,
up-down counter, CTH, and CTC when the operation is started.
Description
Switch Nos. and functions are as follows. The switch consists of 16 bits. The func-
tion of the switch is specified by turning a certain bit ON or OFF.
