9.3 Write Memory Card
To write data to the specified address of the inserted card. The byte is written to the card with LSB
first, i.e., the bit at card address 0 is regarded as the LSB of byte 0.
first, i.e., the bit at card address 0 is regarded as the LSB of byte 0.
The byte at the specified card address is not erased prior to the write operation and, hence, memory
bits can only be programmed from '1' to '0'.

9.4 Erase Non-Application Zone
To erase the data in Non-Application Zones. The EEPROM memory is organized into 16 bit
words. Although erases are performed on single bits the ERASE operation clears an entire word in
the memory. Therefore, performing an Erase on any bit in the word will clear All 16 bits of that
word to the state of ‘1’.
