The AD1835A has 15 control registers, 13 of which are used to
set the operating mode of the part. The other two registers,
ADC Peak 0 and ADC Peak 1, are read-only and should not
be programmed. Each of the registers is 10 bits wide with the
exception of the ADC peak reading registers, which are six bits
wide. Writing to a control register requires a 16-bit data frame
to be transmitted. Bits 15 to 12 are the address bits of the
required register. Bit 11 is a read/write bit. Bit 10 is reserved
and should always be programmed to 0. Bits 9 to 0 contain the
10-bit value that is to be written to the register or, in the case of a
read operation, the 10-bit register contents. Figure 3 shows
the format of the SPI read and write operation.
