According to this Reference Manual, namely Table 3. PMBus Commands, it indicates that WRITE_PROTECT(command 0x10) is not supported.
However, when trying to Read WRITE_PROTECT, 0x00 is returned.
Afterwards, confirming STATUS_CML(command 0x7E), bit7(Unsupported Command) is still 0b0.
The trouble is, when writing blank data (0x00) to WRITE_PROTECT, then checking STATUS_CML, it shows bit7 is now 0b1.
Could we confirm if this is expected behavior?
Thanks team.
