8. Serial Controllers
8.1. Overview
The EM342 has one serial controller, SC1, which provides several options for full-duplex synchronous and
asynchronous serial communications.

SPI (Serial Peripheral Interface), slave only

UART (Universal Asynchronous Receiver/Transmitter)

Receive and transmit FIFOs and DMA channels, SPI and UART modes
Receive and transmit FIFOs allow faster data speeds using byte-at-a-time interrupts. For the highest SPI and
UART speeds, dedicated receive and transmit DMA channels reduce CPU loading and extend the allowable time
to service a serial controller interrupt. Polled operation is also possible using direct access to the serial data
registers. Figure 8.1 shows the components of the serial controllers.
