Register description

R1: DALI Device Counter

After the startup of the KL6811, the number of DALI devices found is stored here. This function can be disabled with bit 4 of the feature register (R32.4).

R6: Diagnostic register

In a later firmware version, the diagnostic register will be used to provide diagnostic information about the state of the DALI master terminal.

R7: Command register

This register can be used to transfer commands to the DALI master terminal.

R8: Terminal description

Register R8 contains the terminal identifier in hexadecimal coding: 0x1A9B (6811_dec)

R9: Firmware version

Register R9 contains the firmware revision level of the terminal in hexadecimal coding, e. g. 0x3144 (12612 _dec).

R10: Shift register length

0x0118

R11: Number of signal channels

0x0118

R12: Minimum data length

0x1818

R13: Data type

Register R13 contains the data type of the Bus Terminal. 0x0004 represents a special function.

R15: Alignment register

R16: Hardware version number

Register R16 contains the hardware revision level of the terminal in hexadecimal coding, e.g. 0x0000 (0_dec).

User register

The user registers of the terminal can be written by the user program in order to change the characteristics of the terminal at run-time.

R31: Code word register

• If you write values into the user registers without previously having entered the user code word (0x1235) in the code word register, these values are only stored in the RAM registers, but not in the EPROM registers and are therefore lost if the terminal is restarted.
• 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 EPROM registers and are therefore retained if the terminal is restarted.

The code word is reset if the terminal is restarted.

R32: Feature register

The feature register specifies the terminal's operating mode.
