The MCP43XX devices support the SPI serial protocol.
This SPI operates in the Slave mode (does not
generate the serial clock).
The SPI interface uses up to four pins. These are:
• CS – Chip Select
• SCK – Serial Clock
• SDI – Serial Data In
• SDO – Serial Data Out

Note 1: If high voltage commands are desired, some type of external circuitry needs to be implemented.

Slave’s Input pin and the Master’s Input pin is
connected to the Slave’s Output pin.
The MCP4XXX SPI’s module supports two (of the four)
standard SPI modes. These are Mode 0,0 and 1,1. The
SPI mode is determined by the state of the SCK pin
