M051 DN/DE
6.11 UART Controller (UART)
6.11.1 Overview
The NuMicro^® M05xxDN/DE provides two channels of Universal Asynchronous
Receiver/Transmitters (UART). UART Controller performs Normal Speed UART, and support flow
control function. The UART Controller performs a serial-to-parallel conversion on data received
from the peripheral, and a parallel-to-serial conversion on data transmitted from the CPU. The
UART controller also supports IrDA SIR Function, LIN master/slave function and RS-485 function
mode. Each UART Controller channel supports seven types of interrupts.
6.11.2 Features
 Full-duplex, asynchronous communications
 Separate receive / transmit 16/16 bytes entry FIFO for data payloads
 Supports hardware auto-flow control and flow control function (CTS, RTS) and
programmable RTS flow control trigger level
 Programmable receiver buffer trigger level
 Supports programmable baud-rate generator for each channel individually
 Supports CTS wake-up function
 Supports 8-bit receiver buffer time-out detection function
 Programmable transmitting data delay time between the last stop and the next start bit by
setting DLY (UA_TOR [15:8]) register
 Supports break error, frame error, parity error and receive / transmit buffer overflow detect
function
 Fully programmable serial-interface characteristics
 Programmable number of data bit, 5-, 6-, 7-, 8- bit character
 Programmable parity bit, even, odd, no parity or stick parity bit generation and
detection
 Programmable stop bit, 1, 1.5, or 2 stop bit generation
 Supports IrDA SIR function mode
 Supports for 3/16 bit duration for normal mode
 Supports LIN function mode
 Supports LIN master/slave mode
 Supports programmable break generation function for transmitter
 Supports break detect function for receiver
 Supports RS-485 function mode
 Supports RS-485 9-bit mode
 Supports hardware or software enable to program RTS pin to control RS-485
transmission direction directly
