6.5.6 Serial Communications Peripherals
Both asynchronous and synchronous serial communications are supported with:
- 10/100 Ethernet MAC with advanced IEEE 1588 PTP hardware and both media independent interface (MII) and reduced MII (RMII) support; integrated PHY provided
- Two CAN 2.0 A and B controllers
- USB 2.0 controller OTG, host, or device with optional high speed using external PHY through ULPI interface
- Eight UARTs with IrDA, 9-bit, and ISO 7816 support
- 1-wire master module that can provide power and data over one bidirectional wire
- Ten I2C modules with four transmission speeds including high-speed mode
- Four Quad Synchronous Serial Interface (QSSI) modules with bi- and quad-SSI support
The following sections provide more detail on each of these communications functions.
