Note:

The thermal shutdown indicator bit THSD is not cleared by

the SRST command, but only after a power-on-reset or through

the CLRFLAG command.

Registers and bits that are subject to the SNAP, UNSNAP

protocol are marked with FRZ in the Type column of the

of the snap, unsnap commands, see the Snapshot Commands

section.

Both the non-volatile memories: NVM1 and NVM2 are

protected through ECC bits. Faults are reported into the SED1,

MED1, SED2, and MED2 bits. After power-up or reset, the

non-volatile memories are read and stored into volatile registers

that are implemented redundantly.

The STAT register contains status bits of read-only type. It can

be read with the RDSTAT command.
