UART - Universal Asynchronous Receiver / Transmitter
The SC1 UART is enabled by writing 1 to SC1_MODE. The SC2 serial controller does not include UART functions.
The UART supports the following features:
8.6.1
The UART uses two signals to transmit and receive serial data:
If RTS/CTS flow control is enabled, these two signals are also used:

Flexible baud rate clock (300 bps to 921.6 kbps)
Data bits (7 or 8)
Parity bits (none, odd, or even)
Stop bits (1 or 2)
False start bit and noise filtering
Receive and transmit FIFOs
Optional RTS/CTS flow control
Receive and transmit DMA channels
TXD (Transmitted Data) – serial data sent by the EM35x
RXD (Received Data) – serial data received by the EM35x
nRTS (Request To Send) – indicates the EM35x is able to receive data
nCTS (Clear To Send) – inhibits sending data from the EM35x if not asserted
