8.5 Register Maps

The ADC32RF8x contains two main SPI banks. The analog SPI bank provides access to the ADC core and the digital SPI bank controls the digital blocks (including the serial JESD interface). Figure 8-64 and Figure 8-65 provide a conceptual view of the SPI registers inside the ADC32RF8x. The analog SPI bank contains the master and ADC pages. The digital SPI bank is divided into multiple pages (the main digital, digital gain, decimation filter, JESD digital, and power detector pages).

GUID-A6D8A024-1308-4EEE-A58D-B16C80468458-low.gif
In general, SPI writes are completed in two steps. The first step is to access the necessary page. The second step is to program the desired register in that page. When a page is accessed, the registers in that page can be programmed multiple times.
Registers in the decimation filter page and the power detector page can be directly programmed in one SPI cycle.
The CH bit is a don't care bit and is recommended to be kept at 0.
Figure 8-64 SPI Registers, Two-Step Addressing
GUID-1743EE9A-5E3C-47C4-887B-8E161DE0CA6B-low.gif
Registers in the decimation filter page and the power detector page can be directly programmed in one SPI cycle.
To program registers in the decimation filter page, set M = 1, CH = 1, A[10] = 0, and A[11] = 0 or 1 for channel A or B. Addressing begins at 50xx for channel A and 58xx for channel B.
To program registers in power detector page, set M = 1, CH = 1, A[10] = 1, and A[11] = 0 or 1 for channel A or B. Addressing begins at 54xx for channel A and 5Cxx for channel B.
