8.2.13.3. 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.
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'.
