EEPROM Status Register (ESTAT)

The ESTAT register deﬁnes the operational status of the module.

CBEIF, PVIOL, and ACCERR are readable and writable, CCIF and BLANK are readable and not writable,

remaining bits read 0 and are not writable in normal mode. FAIL is readable and writable in special mode.
