Notes
1. The ORG pin is used to select between x8
and x16.
When the pin is connected to Vcc, x16 mode
is selected.
Otherwise, the ORG pin should be grounded
in order to select x8 mode.
The interface foe the GSC93BC46/56/66 is accessed through four different signals:
Chip Select (CS), Data Input (DI), Data Output (DO), and Serial Data Clock (SK). The Chip Select (CS) signal
must be pulled high before issuing a command through the Data Input (DI) pin. The Serial Data Clock (SK)
signal is used in conjunction with the Data Input (DI) pin.
