7.3.6. 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.
