UART
UART (universal asynchronous receiver/transmitter) convert parallel data from system bus to serial data through a port. At the destination, a second UART re-assembles this data. Each UART contains a shift register which is the fundamental method of conversion between serial and parallel forms. External signals may be of many different forms, IGEPv2 can handle RS232 and RS485 but not all pads have these standards, Omap UART peripheral use CMOS level voltage (1V8). Omap UART peripheral use four signals:
- UART TX: Transmit signal.
- UART RX: Receive signal.
- UART RTS: Ready to send, used in RS485 and unidirectional communication.
- UART CTS: Clear to send, used in RS485 and unidirectional communication.
