3.5.1.4 Serial Write Operation
All write cycles consist of a command word followed by a data word, both
transmitted to the GF9331 via SDI. The first 16-bit word transmitted following a
falling transition of SCS is a command word. Several write cycles may be
performed while SCS is LOW. See
Figure 3-7: Write Cycle
.

3.5.1.5 Serial Read Operation
All read cycles consist of a command word transmitted to the GF9331 via SDI
followed by a data word transmitted from the GF9331 via SDO. The first 16-bit word
transmitted following a falling transition of SCS is a command word. Several read
cycles may be performed while SCS is LOW. See
Figure 3-8: Read Cycle
