ISD MicroTAD-16M

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 ISD MicroTAD-16M, 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 ISD MicroTAD-16M will be ready for an opera-
tion after T
PUD
(50 ms approximately for 4 KHz sam-
ple rate). The user needs to wait T
PUD
before issuing
an operational command. For example, to play
from address 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.
