6. Write
6. 1 Byte Write
When the master sends a 7-bit device address and a 1-bit read / write instruction code set to "0",
following a start condition, the E2PROM acknowledges it. The E2PROM then receives an 8-bit word
address and responds with an acknowledge. After the E2PROM receives 8-bit write data and responds
with an acknowledge, it receives a stop condition and that initiates the write cycle at the addressed
memory.
During the write cycle all operations are forbidden and no acknowledge is generated.
