SPI-Compatible Serial Interface
Interface the device with a microcontroller using a serial,
4-wire, SPI interface. SPI is a synchronous bus for
address and data transfer, and is used with Motorola or
other microcontrollers that have an SPI port. Four con-
nections are required for the interface: DOUT (serial-
data out); DIN (serial-data in); SCLK (serial clock); and
CS (chip select). In an SPI application, the device acts
as a slave device and the microcontroller acts as the
master. CS is asserted low by the microcontroller to initi-
ate a transfer, and deasserted high to terminate a trans-
fer. DIN transfers input data from the microcontroller to
the device. DOUT transfers output data from the device
to the microcontroller. A shift clock, SCLK, is used to
synchronize data movement between the microcon-
troller and the device. SCLK, which is generated by the
