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 8-50 shows the timing requirements for the serial register write
