• Manufacturer Part Number: mlx16303
• Description: Bi-directional Remote Sensor Unit Interface
• Manufacturer: Melexis Company

CMD_PROG
Enables the communication to send data to the remote units (programming mode).
All other commands are not influenced by the status of the PM bit.
Command
MSB
Answer
MSB
The sent back bit PM can be set to ‘1‘ only if the supply for the programming mode (VP) is higher than
Vvp (9.2 Volts).
CMD_DIAG1
Request of the actual diagnosis result of the bi-directional remote unit interface IC. This means a copy of
the actual status after an error, generated by the continuous diagnosis in the bi-directional remote unit
interface IC, is answered back to the microcontroller. If an error is detected, the diagnosis affected bit is
memorized until the connected microcontroller has sent a CMD_ONOFF with the channel selected and
activated.
If the CMD is sent during the programming mode, the answer will be the same as for a wrong command
