The M8161 ag determines which variable width mode to use. When M8161 = OFF, the 16-bit mode is
enabled, whereby the higher and lower bytes of variables are taken for the operation. When M8161 = ON,
the 8-bit mode is enabled, whereby only the lower bytes of variables are taken for the operation and the
higher bytes are discarded. Therefore, the length of the actually used variable area S is increased.

Bit composition when M8161 = OFF and n = 5
Conversion of D100 to D102
(higher and lower bytes)
Bit composition when M8161 = OFF and n = 6
Conversion of D100 to D102
(higher and lower bytes)
Bit composition when M8161 = ON and n = 5
Conversion of D100 to D104
(lower bytes)
Bit composition when M8161 = ON and n = 6
Conversion of D100 to D105
(lower bytes)
Note:
The RS, HEX, ASCI, and CCD instructions share the M8161 ag. Pay special attention during
programming.
The source data in the S data area must be ASCII characters; otherwise, a conversion error will occur.
If the output data format is BCD, BCD-to-BIN conversion must be performed on the hexadecimal characters
after conversion to get the correct value.
