Register 21: EEPROM Read-Write with Increment (EERDWRINC), offset 0x014
The EERDWRINC register is used to read or write the EEPROM word at the address pointed to by
the EEBLOCK and EEOFFSET registers, and then increment the OFFSET field in the EEOFFSET
register. If the protection or access rules do not permit access, the operation is handled as follows:
if reading is not allowed, the value 0xFFFF.FFFF is returned in all cases; if writing is not allowed,
the EEDONE register is configured to indicate an error. In any case, the OFFSET field is incremented.
If the last value is reached, OFFSET wraps around to 0 and points to the first word.
Note: A read of the EERDWRINC register during the EEPROM initialization sequence is only valid
when the WORKING bit is 0 in EEDONE register:

DescriptionResetTypeNameBit/Field
EEPROM Read or Write Data with Increment
On a read, this field contains the value at the word pointed to by
EEOFFSET. On a write, this field contains the data to be stored at the
word pointed to by EEOFFSET. For writes, configuring this field starts
the write process. If protection and access rules do not permit reads,
all 1s are returned. If protection and access rules do not permit writes,
the write fails and the EEDONE register indicates failure.
Regardless of error, the OFFSET field in the EEOFFSET register is
incremented by 1, and the value wraps around if the last word is reached.
