product. In this example, we will assume the user wants an attenuation of –12 dB. For that
setting, D11 should be set to ONE, D12 should be set to ONE, and D13 should be set to a ZERO.
8.
Select the VOLUME CONTROL path through the OUTPUT MUX—These are bits D3 and D4,
respectively, of CFG0. They should be set to the state where D3 is ZERO and D4 is a ZERO to
select the VOLUME CONTROL.
9.
Power up the SPEAKER amplifier and select the HIGH GAIN mode—Bits OPA0 and OPA1
control the state of the speaker (SP+ and SP–) and AUX OUT outputs. These are bits D1 and D2
of CFG0. They must be set to the state where D1 is ONE and D2 is ZERO to power-up the
speaker outputs in the HIGH GAIN mode and to power-down the AUX OUT.
To set up the chip for Memo or Call Playback, the configuration registers are set up as follows:
CFG0=0010 0100 0010 0010 (hex 2422).
CFG1=0101 1001 1101 0001 (hex 59D1).
Only those portions necessary for this mode are powered up.
3.11 MESSAGE CUEING
Message cueing allows the user to skip through analog messages without knowing the actual physical
location of the message. This operation is used during playback. In this mode, the messages are skipped
512 times faster than in normal playback mode. It will stop when an EOM marker is reached. Then, the
internal address counter will be pointing to the next message.
