3. Slave responds back with an ACK.
4. Wait for SCL HIGH.
5. Send Digital Mode command – 0X80h, 0XC0h
6. Slave responds with an ACK.
7. Wait for SCL HIGH.
8. Send Slave Address command – 0X80h
9. Slave responds with an ACK.

11. Host sends a Digital Erase command to Slave - (Command Byte = 0XD1h).
12. Slave responds with an ACK.
13. Wait for SCL HIGH.
14. Host sends a byte to Slave - (High Address Byte = 0000h).
15. Slave responds with an ACK.
