关于错误起始位的判断,下面引自 datasheet
The start bit is valid if U0Rx or U1Rx is still low on the eighth cycle of Baud16, otherwise a false start bit is detected and it is ignored. Start bit errors can be viewed in the UART Receive Status (UARTRSR) register (see page211).
然而在 P211 UARTRSR 的讲述中,却没有这个错误,只有 OE,BE,PE,FE. 而 ZLG 翻译的资料也是这么说的 |
