UART S3C84E5/C84E9/P84E9

UART CONTROL REGISTER (UARTCON)
The control register for the UART is called UARTCON at address F6H. It has the following control functions:
— Operating mode and baud rate selection
— Multiprocessor communication and interrupt control
— Serial receive enable/disable control
— 9th data bit location for transmit and receive operations (mode 2)
— Parity generation and check for transmit and receive operations (mode 2)
— UART transmit and receive interrupt control
A reset clears the UARTCON value to "00H". So, if you want to use UART module, you must write appropriate value
to UARTCON.
