Bit composition in the case of n=K4
• When issuing as BCD data by printer or the like, before execution of this instruction, you must convert from
BIN to BCD.
3. <8-bit conversion mode> When M8161=ON (M8161 is used commonly with RS, HEX, CCD,
CRC instructions)
Each digit of HEX data stored after the device specified by is converted into ASCII, and stored in lower 8
bits (bytes) in each device after the one specified by . The number of digits (characters) to be converted
is specified by n.
In the device specified by , higher 8 bits are 0.
M8161 is used commonly with RS, HEX, CCD, CRC instructions. When using in 8 bits, you must keep always
ON.
M8161 is cleared when changed from RUN to STOP.
Operation
In the case of the program shown below, the conversion is executed as follows.
