Original GitHub issue: https://github.com/hirschmann/nbfc/issues/1355

Describe the bug
Attempting to modify a register via ec-probe for fan control. It doesn't write to the desired hexadecimal.

To Reproduce

Write to a register: ec-probe write 0xAF 0x06
Read the register: ec-probe read 0xAF

Expected behavior
Should write the hexadecimal to the register as expected.

System information

operating system: Arch Linux
NBFC version: 1.6.3.0
log files (see NBFC files and directories overview):

Additional context
Tried any other register. None of them write either. Here is the verbose when writing:

Turns out the value I was modifying was getting overwritten by another registry's hexadecimal (0x61). Modifying 0x61's hexadecimal directly also modifies the 0xAF registry and AIPT's level.
