digital port control registers
Peripheral file frame 2 contains the digital I/O pin configuration and control registers. Table 11 shows the specific
addresses, registers, and control bits within this peripheral file frame. Table 12 shows the port configuration
register setup.

serial peripheral interface
The SPI is a high-speed synchronous serial I/O port that allows a serial bit stream of programmed length (one
to eight bits) to be shifted into and out of the device at a programmable bit transfer rate. The SPI normally is
used for communications between the microcontroller and external peripherals or another microcontroller.
Typical applications include external I/O or peripheral expansion by way of devices such as shift registers,
display drivers, and A/D converters. Multi-device communications are supported by the master/slave operation
of the SPI. The SPI module features include the following:
Three external pins
SPISOMI: SPI slave output/master input pin or general-purpose bidirectional I/O pin
SPISIMO: SPI slave input/master output pin or general-purpose bidirectional I/O pin
SPICLK: SPI serial clock pin or general-purpose bidirectional I/O pin
Two operational modes: Master and slave
