SPI
SCI
I2C
The SPI is a high-speed, synchronous serial I/O port that allows a serial bit stream
of programmed length (one to sixteen bits) to be shifted into and out of the device at
a programmable bit-transfer rate. Normally, the SPI is used for communications
between the MCU and external peripherals or another processor. Typical
applications include external I/O or peripheral expansion through devices such as
shift registers, display drivers, and ADCs. Multi-device communications are
supported by the master/slave operation of the SPI. The SPI contains a 4-level
receive and transmit FIFO for reducing interrupt servicing overhead.
The serial communications interface is a two-wire asynchronous serial port,
commonly known as UART. The SCI contains a 4-level receive and transmit FIFO
for reducing interrupt servicing overhead.
The inter-integrated circuit (I2C) module provides an interface between a MCU and
other devices compliant with Philips Semiconductors Inter-IC bus (I2C-bus)
specification version 2.1 and connected by way of an I2C-bus. External components
attached to this 2-wire serial bus can transmit/receive up to 8-bit data to/from the
MCU through the I2C module. The I2C contains a 4-level receive and transmit FIFO
for reducing interrupt servicing overhead.
