1. Host executes I
2. Send Slave Address with R/W bit = “0” (Write)
3. Slave responds back with an ACK.
4. Wait for SCL HIGH
5. Host sends a byte to Slave - (Command Byte = C9h)
6. Slave responds with an ACK
7. Wait for SCL HIGH
8. Host sends a byte to Slave - (High Address Byte)
9. Slave responds with an ACK
10. Wait for SCL HIGH
11. Host sends a byte to Slave - (Low Address Byte)
12. Slave responds with an ACK
13. Wait for SCL HIGH
14. Host sends a byte to Slave - (First 8 bits of digital information)
15. Slave responds with an ACK
16. Wait for SCL HIGH
17. Steps 14, 15 and 16 are repeated until last byte is sent and acknowledged
