6.1.3 Connection of EEPROM
As described previously the W83791SD/SG could connect W55FXX to store voice data. To
expand the storage capacity, users could select more than one W55FXX to connect together.
The maximum capacity could be up to 16Mbit. Following is the connection chart of W55FX
with W83791SD/SG.
