UART (
× 2)
The UART is a serial I/O port for asynchronous (start-stop) communication or clock-synchronous communication.
The UART has the following features :
Full-duplex double buffering
Capable of asynchronous (start-stop bit) and CLK-synchronous communications
Support for the multiprocessor mode
Various method of baud rate generation :
- External clock input possible
- Internal clock (a clock supplied from 16-bit reload timer can be used.)
- Embedded dedicated baud rate generator
Note : Assuming internal machine clock frequencies of 6 MHz, 8 MHz, 10 MHz, 12 MHz, and 16 MHz.
Error detection functions (parity, framing, overrun)
NRZ (Non Return to Zero) signal format
Interrupt request :
- Receive interrupt (receive complete, receive error detection)
- Transmit interrupt (transmission complete)
- Transmit / receive conforms to extended intelligent I/O service (EI2OS).
