NuMicro M058S Series Datasheet
6.10 UART Interface Controller (UART)
6.10.1 Overview
The NuMicro^TM M058S 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.
6.10.2 Features
 Full duplex, asynchronous communications
 Separate receive / transmit 16/16 bytes entry FIFO for data payloads
 Supports hardware auto flow control/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 UA_TOR [DLY] 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 9bit mode
 Supports hardware or software enable to program RTS pin to control RS-485
transmission direction directly
