Introduction
104
The serial input/output port (SIOP) is a 3-wire master/slave
communication port with serial clock, data input, and data output
connections. The SIOP enables high-speed synchronous serial data
transfer between the MCU and peripheral devices. Shift registers used
with the SIOP can increase the number of parallel I/O pins controlled by
the MCU. More powerful peripherals such as analog-to-digital
converters and real-time clocks are also compatible with the SIOP.
