5.3.1
To write a byte in the MCP98243 EEPROM, the master
has to specify the memory location or address. Once
the address byte is transmitted correctly followed by a
word address, the word address is stored in the
EEPROM address pointer. The following byte is data
to be stored in the specified memory location.
