Register 23: EEPROM Support Control and Status (EESUPP), offset 0x01C
The EESUPP register indicates if internal operations are required because an internal copy buffer
must be erased or a programming failure has occurred and the operation must be completed. These
conditions are explained below as well as in more detail in the section called “Error During
Programming” on page 619.
■ If either PRETRY or ERETRY is set indicating that an operation must be completed, setting the
START bit causes the operation to be performed again
■ The PRETRY and ERETRY bits are cleared automatically after the failed operation has been
successfully completed.
These bits are not changed by reset, so any condition that occurred before a reset is still indicated
after a reset.
