78 / 107 page NUC100/120xxxDN Aug 31, 2015 Page 78 of 107 Rev 1.01 SIR Protocol encoder/decoder. The IrDA SIR Protocol encoder/decoder is half-duplex only. So it cannot transmit and receive data at the same time. The IrDA SIR physical layer specifies a minimum 10ms transfer delay between transmission and reception, and this delay feature must be implemented by software. The alternate function of UART controllers is LIN (Local Interconnect Network) function. The LIN mode is selected by setting the UA_FUN_SEL[1:0] to ’01’. In LIN mode, 1 start bit and 8 data bits format with 1 stop bit are required in accordance with the LIN standard. For NuMicro ® NUC100 series, another alternate function of UART controllers is RS-485 9-bit mode, and direction control provided by /RTS pin or can program GPIO (PB.2 for UART0_nRTS and PB.6 for UART1_nRTS) to implement the function by software. The RS-485 mode is selected by setting the UA_FUN_SEL register to select RS-485 function. The RS-485 transceiver control is implemented using the /RTS control signal from an asynchronous serial port to enable the RS- 485 transceiver. In RS-485 mode, many characteristics of the receiving and transmitting are same as UART. 6.14.2 Features Full duplex, asynchronous communications Separates receive / transmit 64/16/16 bytes (UART0/UART1/UART2) entry FIFO for data payloads Supports hardware auto flow control/flow control function (CTS, RTS) and programmable RTS flow control trigger level (UART0 and UART1 support) Programmable receiver buffer trigger level Supports programmable baud-rate generator for each channel individually Supports CTS wake-up function (UART0 and UART1 support) Supports 7-bit receiver buffer time-out detection function UART0/UART1 can through DMA channels to receive/transmit data 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 data bit length, 5-, 6-, 7-, 8-bit character – Programmable parity bit, even, odd, no parity or stick parity bit generation and detection – Programmable stop bit length, 1, 1.5, or 2 stop bit generation IrDA SIR function mode – Supports 3-/16-bit duration for normal mode LIN function mode – Supports LIN master/slave mode – Supports programmable break generation function for transmitter – Supports break detect function for receiver RS-485 function mode. |
