being accessed. If the write command was requested, the values from “fm_data“ or “fm_data_16“are written to the address listed
in the “*fm_address“ or “*fm_address_16“variables.
0x1), because first the analog die has to be put in low power mode by writing 0x1 to the Mode Control Register. The STOP
instruction is then executed.

compilation in the LIN software driver. The baud rate can be changed in the file “slave.cfg“. The baud rate is defined by the
following formula:
based on the LIN 1.3 protocol specification.

The variables “*fm_address“ (pointer to char) or “*fm_address_16“(pointer to int) have information on the register addresses
Finally, the variable “fm_status“ is set to “done”. The FreeMASTER then knows that the data was updated.
This code section is also checked if there was a request to enter the STOP mode (if fm_address == 0x216 and fm_data ==
As previously mentioned, LIN communication parameters (baud rate, messages size, messages ID) are set before code
SciBaudRate is the value written to the SCI baud rate register and BR is the real baud rate value (9600 or 19200).
The size of the messages and the ID of the messages can be changed or added in the file “slave.id“. The ID shall be assigned,
