It should be noted that the Parity Error (PE) bit (LSR[2]) will be set if a break interrupt has occurred, as indicated by Break Interrupt (BI) bit (LSR[4]). In this situation, the Parity Error bit is set depending on the combination of EPS (LCR[4]) and DLS (LCR[1:...
BIT-2:Parity Error (PE):此位指示接收数据的奇偶校验是否错误。如果接收到的数据的奇偶校验与期望的奇偶校验不匹配,此位将被置位。 BIT-3:Framing Error (FE):此位指示接收数据中的帧错误。如果接收到的数据中有帧错误,此位将被置位。 BIT-4:Break Interrupt (BI):此位指示是否检测到了中断信号。如果接收...

The error means the data in the shift register are lost, the transfer is terminated with the error. You can call another Receive() function. As I said, you can avoid the issue by increasing the interrupt priority or by using DMA. Regards, Daniel 0 Kudos Reply 05-04-2023 08:06 ...
The reported status information includes the type and condition of the transfer operations performed by the UART, as well as any error conditions (parity, overrun, framing or break interrupt). The D16750 includes a programmable baud rate generator, which is capable of dividing the timing ...
halted, the UART status register is reset from the transmit function call, and the hardware interrupt is enabled after clearing any pending interrupts that occurred during the transmit functions (if a low bit was transmitted, the IFR register flag will be set even while the interrupt is masked)...
