6.2 UARTs
The SC1x3 provides four independent asynchronous serial ports. These ports provide full-duplex, bidirectional
data transfer using several industry-standard communications protocols. The serial ports can be used as
sources or destinations of DMA transfers.
The asynchronous serial ports support the following features:
Full-duplex operation
DMA to and from the serial ports
7-bit or 8-bit data transfers
Odd, even, mark, space or no parity
One or two stop bits
Long or short break character recognition
Error detection
- Parity errors
- Framing errors
- Overrun errors
- Break character recognition
Hardware handshaking with the following selectable control signals:
- Clear-to-send (CTS)
- Ready-to-send (RTS)
Separate maskable interrupts for each port
Independent baud rate generators
Maximum baud rate of 1/16th of the CPU clock
Double-buffered transmit and receive
Programmable user call-back function for transmit and receive
6.2.1 RTOS Update via serial ports
The RTOS version can be updated via UART0 (COM0) or UART1 (COM1), see chapter 5 System Start-up
Configuration).
