KL8548 - Register description
The registers are used for the parameterization of the Bus Terminals and are available for each channel. They can be read or written by means of the register communication.
R7: Command register
Not used.
R8: Terminal description
The name of the terminal is contained in register R8.
KL8548: 0x2164 (KL8548dec)
R9: Firmware version
Register R9 contains the ASCII coding of the terminal's firmware version, e.g. 0x3141 = '1A'. The '0x31' corresponds here to the ASCII character '1', while the '0x41' represents the ASCII character 'A'.
This value cannot be changed.
R12: Minimum data length of a channel
R16: Hardware version number
Register R16 contains the hardware version of the terminal.
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.
R32: Feature register
With this register you can switch various features for this channel on or off.

R33: User switch-on value
If the user switch-on value has been enabled with bit R32.8 of the feature register, the terminal sets its output to the user switch-on value in place of the manufacturer switch-on value on the occurrence of a system reset or a watchdog timer overflow (terminal has not received any process data for 100 ms).
