The internal registers can be
programmed following these steps:
- Drive the SEN pin low
- Set the R/W bit to 0 (bit A15 of the 16-bit address) and bits
A[14:12] in address field to 0.
- Initiate a serial interface cycle by specifying the address of
the register (A[11:0]) whose content is written and
- Write the 8-bit data that are latched in on the SCLK rising
edges
Figure 7-48 shows the timing
requirements for the serial register write operation.
