10.2 Serial Peripheral Interface (SPI)
10.2.1
Protocol description
The DAC1627D1G25 serial interface is a synchronous serial communication port ensures
easy interface with many industry microprocessors. It provides access to the registers that
define the operating modes of the chip in both write and read mode.
This interface can be configured as a 3-wire type (pin SDIO as bidirectional pin) or 4-wire
type (pins SDIO and SDO as unidirectional pins, input and output port respectively). In
both configurations, SCLK acts as the serial clock and SCS_N as the serial chip select.
Figure 3
shows the SPI protocol. Each read/write operation is followed by an SCS_N
signal and enabled by a LOW assertion to drive the chip with two to five bytes, depending
on the content of the instruction byte (see
Table 7
).
R/W indicates the mode access (see
Table 6
)
Table 6.

Table 7
shows the number of bytes to be transferred. N1 and N0 indicate the number of
bytes transferred after the instruction byte.

A[4:0] indicates which register is being addressed. If a multiple transfer occurs, this
address concerns the first register. Next are those which follow directly in a decreasing
order (see
Table 23
,
Table 55
and
Table 79
).
