The S3C2443 UART includes programmable baud rates, infrared (IR) transmit/receive,
one or two stop bit insertion, 5-bit, 6-bit, 7-bit or 8-bit data width and parity
checking.
Each UART provides a baud-rate generator, transmitter, receiver and a control unit.
The baud-rate generator can be clocked by PCLK or EPLLCLK/n. UEXTCLK (external
input clock) is used on the module as GPIO. The transmitter and the receiver contain
64-byte FIFOs and data shifters. Data is written to FIFO and then copied to the
transmit shifter before being transmitted. The data is then shifted out by the
transmit data pin (TxDn). Meanwhile, received data is shifted from the receive data
pin (RxDn), and then copied to FIFO from the shifter.
The S3C2443 UART block supports also infra-red (IR) transmission and reception,
which can be selected by setting the Infra-red-mode bit in the UART line control
register (ULCONn).
There are four UART baud rate divisor registers including UBRDIV0, UBRDIV1, UBRDIV2
and UBRDIV3 in the UART block. The value stored in the baud rate divisor register
(UBRDIVn) and dividing slot register (UDIVSLOTn), are used to determine the serial
Tx/Rx clock rate (baud rate) as follows:
DIV_VAL = (SRCCLK / (baud rate x 16)) -1
Where DIV_VAL should be from 1 to (216-1) and SRCCLK is either PCLK or divided EPLL
clock.
DIV_VAL can be programmed in the S3C2443 registers the following way:
DIV_VAL = UBRDIVn + (num of 1's in UDIVSLOTn)/16
