8.4.3.1 Serial Register Write: Analog Bank

The internal register of the ADC32RF8x analog bank (Figure 137) can be programmed by:

1. Driving the SEN pin low.

2. Initiating a serial interface cycle selecting the page address of the register whose content must be written. To

select the master page: write address 0012h with 04h. To select the ADC page: write address 0011h with

FFh.

3. Writing the register content. When a page is selected, multiple registers located in the same page can be

programmed.

8.4.3.2 Serial Register Readout: Analog Bank

Contents of the registers located in the two pages of the analog bank (Figure 138) can be readback by:

1. Driving the SEN pin low.

2. Selecting the page address of the register whose content must be read. Master page: write address 0012h

with 04h. ADC page: write address 0011h with FFh.

3. Setting the R/W bit to 1 and writing the address to be read back.

4. Reading back the register content on the SDOUT pin. When a page is selected, the contents of multiple

registers located in same page can be readback.
