R31: Code word register
• If you write values into the user registers without first entering the user code word (0x1235) into the
code word register, the terminal will not accept the supplied data.
• If you write values into the user registers and have previously entered the user code word (0x1235) in
the code word register, these values are stored in the RAM registers and in the SEEPROM registers
and are therefore retained when the terminal is restarted.
The code word is reset when the terminal is restarted.
