S3C2410A
UART TRANSMIT BUFFER REGISTER (HOLDING REGISTER & FIFO REGISTER)
There are three UART transmit buffer registers including UTXH0, UTXH1 and UTXH2 in the UART block.
UTXHn has an 8-bit data for transmission data.
NOTE:
UART RECEIVE BUFFER REGISTER (HOLDING REGISTER & FIFO REGISTER)
There are three UART receive buffer registers including URXH0, URXH1 and URXH2 in the UART block.
URXHn has an 8-bit data for received data.

(L): The endian mode is Little endian.
(B): The endian mode is Big endian.
When an overrun error occurs, the URXHn must be read. If not, the next received data will also make an
overrun error, even though the overrun bit of UERSTATn had been cleared.
