Call Record
The call record mode adds the ability to record the incoming phone call. In most applications, the
5008 would first be set up for Feed Through Mode as described above. When the user wishes to
explanation, we will use the 6.4 kHz sample rate during recording.
block diagram of the ISD5008 shows that the Multilevel Storage array is always driven from the
M2 SUMMING amplifier. The path traces back from there through the LOW PASS Filter, TH
FILTER MUX, THE SUM1 SUMMING amplifier, the SUM1 MUX, then from the ANA in amplifier. Feed
Mode has already powered up the ANA IN amp so we only need to power up and enable the
th to the Multilevel Storage array from that point:
the SUM1 MUX. These are bits D9 and D10 respectively of CFG1 and they should be set
to the state where both D9 and D10 are ZERO to select the ANA IN path.

uld be necessary to load both registers.
