4.5 UART Interface
The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that
conforms to the RS-232 Interface protocol. The module has 3 UARTs which provides 2.85 V CMOS level
outputs and 2.85V CMOS input levels. All the control signals of the RS-232 are active low, however the
data signals, RXD and TXD, are active high.
UART1 which has 512 bytes for Tx and Rx FIFO, supports high speed data communication up to
230.4kbps, program download and diagnostic monitor function.
UART2 and 3 which 64 bytes for T/Rx FIFO, support low speed data communication up to 115.2kbps,
program download and diagnostic monitor function.
The UART features hardware handshaking, programmable data sizes, programmable stop bits, and odd,
even, no parity.
