UART

CL-SOM-AM57x provides up to 9 UART ports. The functionality is derived from the UART
modules integrated into the Sitara AM57x SoC. One UART port supports IrDA features. The
following general features are supported:

16C750 compatibility

Baud rate from 300 bps up to 12 Mbps

Flow control: Hardware (RTS/CTS) or software (XON/XOFF)

UART1 module has extended modem control signals (DCD, RI, DTR, DSR)

Support of IrDA 1.4 slow infrared (SIR), medium infrared (MIR), and fast infrared (FIR)
communications (UART3 only).

Support of consumer infrared (CIR) for remote control applications (UART3 only)
For additional details on UART, please refer to the Sitara AM57x technical reference manual. The
tables below summarize the UART interface signals
