Data EEPROM
The internal data EEPROM offers 2 pages of 512 bits each. Both pages are organized as
32
× 16 bit words. The programming voltage as well as the write cycle timing is generated on
chip.
If it is necessary to be compatible with the ROM parts, only the default page must be used with
the flash part. Also for compatibility reasons the access to the EEPROM is handled via the MCL
(serial interface) as in the corresponding ROM parts.
The page select is performed by either writing ''01h'' (page 1) or ''09h'' (page 0) to the EEPROM.
