SDA LINE
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 S-24C04C acknowledges it. The S-24C04C then receives an 8-bit word address and responds with
an acknowledge. After the S-24C04C 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.
