1.7. Serial Ports
Serial peripherals included on the devices are two Enhanced Full-Duplex UARTs, SPI Bus, and SMBus/
I2C. Each of the serial buses is fully implemented in hardware and makes extensive use of the CIP-51's
interrupts, thus requiring very little intervention by the CPU. The serial buses do not "share" resources
such as timers, interrupts, or Port I/O, so any or all of the serial buses may be used together with any other.
