Voice Solutions in Silicon
1.
Message Cueing can be selected only at the
beginning of a play operation.
2.
As the Interrupt data is shifted out of the ISD4004,
control and address data is being shifted in. Care
should be taken such that the data shifted in is
compatible with current system operation. It is
possible to read interrupt data and start a new
operation at the same time. See Figure 5 through
Figure 8 for Opcode format.
POWER-UP SEQUENCE
The ISD4004 will be ready for an operation after
T
PUD
(25 ms approximately for 8 KHz sample rate).
The user needs to wait T
PUD
before issuing an opera-
tional command. For example, to play from ad-
dress 00 the following programing cycle should be
used.
Playback Mode
1.
Send POWERUP command.
2.
Wait T
PUD
(power-up delay).
3.
Send SETPLAY command with address 00.
4.
Send PLAY command.
The device will start playback at address 00 and it
will generate an interrupt when an EOM is
reached. It will then stop playback.
Record Mode
1.
Send POWERUP command.
2.
Wait T
PUD
(power-up delay).
3.
Send POWERUP command.
4.
Send SETREC command with address 00.
5.
Send REC command.
The device will start recording at address 00 and it
will generate an interrupt when an overflow is
reached (end of memory array). It will then stop re-
cording.
