PLAYBACK MODE
The command sequence for an analog Playback operation can be handled several ways. One
technique is to do a Load Address (81h), which requires sending a total of four bytes, followed by a
Play Analog, which is a Command Byte (A8h) preceded by the Slave Address Byte. This is a total of six
bytes plus the times for Start, ACK, and Stop.
Another approach for an analog Playback operation is via a single four byte exchange, which consists
of the Slave Address (80h), the Command Byte (A9h) for Play Analog @ Address, and the two address
bytes.
RECORD MODE
The command sequence for an Analog Record is a four byte sequence consisting of the Slave
Address (80h), the Command Byte (91h) for Record Analog @ Address, and the two address bytes.
