Number of characters specified and result of conversion
"." is 0.
• When the input data is BCD, after execution of this instruction, you must convert from BCD to BIN.
• In the case of HEX instruction, if the data stored in the device specified by is not ASCII code, it is an
operation error, and HEX conversion is disabled. In particular, if M8161 is OFF, you must store the ASCII
code also in the higher 8 bits of the device specified by .
3. <8-bit conversion mode> When M8161=ON(M8161 is used commonly with RS, ASCI, CCD,
CRC instructions)
ASCII characters stored in lower 8 bits in are converted into HEX data, and transferred to 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 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.
