A single byte may be written to the Command Byte Register in order to power up the device, start
or stop Analog Record (if no address information is needed), or do a Message Cueing function.
The Command Byte Register is loaded as follows:
1. Host executes I
2. Send Slave Address with R/W bit = “0” (Write) [80h]
3. Slave responds back with an ACK.
4. Wait for SCL to go HIGH
5. Host sends a command byte to Slave
6. Slave responds with an ACK
7. Wait for SCL to go HIGH
8. Host executes I
For the normal addressed mode the Registers are loaded as follows:
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 to go HIGH
5. Host sends a byte to Slave - (Command Byte)
6. Slave responds with an ACK
7. Wait for SCL to go HIGH
8. Host sends a byte to Slave - (High Address Byte)
9. Slave responds with an ACK
10. Wait for SCL to go HIGH
11. Host sends a byte to Slave - (Low Address Byte)
12. Slave responds with an ACK
13. Wait for SCL to go HIGH
