11.6 Serial Peripheral Interface (SPI)
11.6.1 Register description
The ADC1215S serial interface is a synchronous serial communications port that allows
for easy interfacing with many commonly-used microprocessors. It provides access to the
registers that control the operation of the chip.
This interface is configured as a 3-wire type (SDIO as bidirectional pin)
Pin SCLK is the serial clock input and CS is the chip select pin.
Each read/write operation is initiated by a LOW level on CS. A minimum of three bytes will
be transmitted (two instruction bytes and at least one data byte). The number of data
bytes is determined by the value of bits W1 and W2 (see Table 17).
[1]
Bit R/W indicates whether it is a read (1) or a write (0) operation.
[2]
Bits W1 and W0 indicate the number of bytes to be transferred after the instruction byte (see Table 17).
