FUNCTIONAL DESCRIPTION OF THE SPI
Serial Peripheral Interface (SPI)
This device uses a standard SPI to communicate with a microcontroller. The SPI can be driven by a microcontroller
with its SPI peripheral running in either of the two following modes: CPOL = CPHA = 0 or CPOL = CPHA = 1.
For these two modes, input data is sampled by the low to high transition of the clock CLK, and output data is
changed from the high to low transition of CLK.
The difference of these two modes is the standby polarity of the CLK. For CPOL = 0 the CLK remains low and
for CPOL = 1 the CLK remains high.
This device is not limited to microcontrollers with a build-in SPI. Only three CMOS-compatible output pins and
one input pin will be needed to communicate with the device. A fault condition can be detected by setting CSN
to low. If CSN = 0, the DO-pin will reflect the status bit 0 (fault condition) of the device which is a logical-or of all
bits in the status registers 0 and 1. The microcontroller can poll the status of the device without the need of a
full SPI-communication cycle.
Note:
In contrast to the SPI-standard the least significant bit (LSB) will be transfered first (see. FIGURE 8).
Chip Select not (CSN)
The input pin is used to select the serial interface of this device. When CSN is high, the output pin (DO) will be
in high impedance state. A low signal will activate the output driver and a serial communication can be started.
Serial Data In (DI)
The input pin is used to transfer data serial into the device. The data applied to the DI will be sampled at the
DI (pin 7)DO (pin 17)
