SPI PROTOCOL DESCRIPTION
The SPI interface has a full-duplex, three-wire
synchronous, 16-bit serial synchronous interface data
transfer and four I/O lines associated with it: Chip Select (
CS
),
Serial Clock (SCLK), Serial Input (SI), and Serial Output
(SO). The SI/SO pins of the 33970 follow a first in/first out
(D15/D0) protocol with both input and output words
transferring the most significant bit first. All inputs are
compatible with 5.0 V CMOS logic levels.
LOGIC COMMANDS AND REGISTERS
This section provides a description of the 33970 SPI behavior. To follow the explanations below, refer to
Table 5
and to the
timing diagrams shown in
Figure 6
and
Figure 7
.

Description
CS
(1-to-0)
SO pin is enabled.
CS
(0-to-1)
33970 configuration and desired output states are transferred and executed according to the data in
the Shift registers.
SO
Will change state on the rising edge of the SCLK pin signal.
SI
Will accept data on the falling edge of the SCLK pin signal.
CS
