6.3.6 Power-up Sequence
This sequence prepares the ISD5100 Series for an operation to follow, waiting the Tpud time before
sending the next command sequence.
1. Send I
2
C POWER UP
2. Send one byte 10000000 {Slave Address, R/W = 0} 80h
3. Slave ACK
4. Wait for SCL High
5. Send one byte 10000000 {Command Byte = Power Up} 80h
6. Slave ACK
7. Wait for SCL High
8. Send I
2
C STOP
Playback Mode
The command sequence for an analog Playback operation can be handled several ways. The most
straightforward approach would be to incorporate 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.
