13.6.1 Register description
13.6 Serial Peripheral Interface (SPI)
Table 13.
The ADC1413D serial interface is a synchronous serial communications port allowing for
easy interfacing with many industry microprocessors. It provides access to the registers
that control the operation of the chip in both read and write modes.
This interface is configured as a 3-wire type (SDIO as bidirectional pin).
SCLK acts as the serial clock, and CS acts as the serial chip select bar.
Each read/write operation is sequenced by the CS signal and enabled by a LOW level to
to drive the chip with 2 bytes to 5 bytes, depending on the content of the instruction byte
(see
