Hi @bia-bonobo ,
A more precise description would be that FBB_DISABLE is specific to the chip itself and is therefore factory-configured. When the RT1170 needs to operate in overdrive mode, it must read FBB_DISABLE first and then determine whether to enable FBB.
There is no publicly available list corresponding to part numbers; instead, this depends on the specific characteristics of the process/chip itself. Therefore, as described in the datasheet, the software flow should first read FBB_DISABLE.
Best regards,
Gavin
