Application of SRA/SLA instructions
■ Fetching four-digit data of the BCD digital switch (inputs 0004 through 0011
for low-order 2 digits and 0100 through 0107 for high-order 2 digits) to
transfer them as a counter setting value
■ Separate input of BCD
Fetches only 2 digits of the BCD digital switch (0112 to 0115 for the 1st digit, 0000 to
0003 for the 2nd digit) and sets it as the counter value.

Converts the data of internal register to BIN data and writes it into
C001.
Sets C001.
Sends the data of 0112 to 0115 to internal register.
Shifts the value of internal register to right by 12 bits and writes it
into DM0000.
Sends the data of 0000 to 0003 to internal register.
Shifts the data of internal register to left by 4 bits, ORs the internal
register data and the data of DM0000, and sends the ORed data to
the internal register.
