3. 8-bit conversion mode (while M8161 is ON)
(M8161 is used also for the RS, HEX, CCD and CRC instructions.)
Each digit of hexadecimal data stored in and later is converted into an ASCII code, and transferred to low-order
8 bits of each device and later. The number of digits (characters) to be converted is specified by "n". "0" is
stored in high-order 8 bits of each device and later.
M8161 is used also for the RS, HEX, CCD and CRC instructions. When using the 8-bit mode, set M8161 to normally
ON. M8161 is cleared when the PLC mode is changed from RUN to STOP.
Operation
In the following program, conversion is executed as follows:

D100 = 0ABCH
D101 = 1234H
D102 = 5678H

Bit configuration in the case of "n = K2"
• When outputting data in the BCD format for a printer, for example, it is necessary to convert binary data into BCD
data before executing this instruction.
