CCD, CRC instructions)
ASCII characters stored in higher and lower 8 bits (bytes) in the device specified by are converted into
HEX data, and transferred to the device specified by in every four digits. The number of characters to be
converted is specified by n.
M8161 is used commonly with RS, ASCI, CCD, CRC instructions. When using in 16 bits, you must keep
always OFF.
M8161 is cleared when changed from RUN to STOP.
