10.3 Serial Peripheral Interface (SPI)
10.3.1
Protocol description
The DAC1408D650 serial interface is a synchronous serial communication port allowing
easy interfacing with many industry microprocessors. It provides access to the registers
that define the operating modes of the chip in both Write mode and Read mode.
This interface can be configured as a 3-wire type (SDIO as bidirectional pin) or a 4-wire
type (SDIO and SDO as unidirectional pin, input and output port respectively). In both
configurations, SCLK acts as the serial clock and SCS_N acts as the serial chip select
bar.
Each read/write operation is sequenced by the SCS_N signal and enabled by a LOW
assertion to drive the chip with two bytes to five bytes, depending on the content of the
instruction byte (see
Table 8
).

In
Table 8
below, N1 and N0 indicate the number of bytes transferred after the instruction
byte.

A[4:0] indicates which register is being addressed. In the case of a multiple transfer, this
address points to the first register to be accessed. The address is then internally
decreased after each following data phase.
R/W indicates the mode access, (see
Table 7
).
