6.2 Programmable Serial Controllers
The SC2x3 supports six PSCs (Programmable Serial Controllers). Each can be configured to operate in
different modes. PSCs support both synchronous and asynchronous protocols. They are used to interface,
modems, SPI or CAN.
6.2.1 UARTs
The SC2x3 provides six asynchronous serial ports through the PSCs. These ports provide full-duplex,
bidirectional data transfer using several industry-standard communications protocols.
The asynchronous serial ports support the following features:
Full-duplex operation
512 byte FIFO
7-bit or 8-bit data transfers
Odd, even, mark, space, no parity or multidrop mode
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)
-
Data Carrier Detect (DCD)
Separate maskable interrupts for each port
Independent baud rate generators
Maximum baud rate of 4.125 MBits/s
Double-buffered transmit and receive
