TI中文支持网本人没有使用FIFO功能。配置如下
ScibRegs.SCICCR.all =0x0007; // 1 stop bit, No loopback
// No parity,8 char bits,
// async mode, idle-line protocol
ScibRegs.SCICTL1.all =0x0003; // enable TX, RX, internal SCICLK,
// Disable RX ERR, SLEEP, TXWAKE
ScibRegs.SCICTL2.bit.TXINTENA =1;
ScibRegs.SCICTL2.bit.RXBKINTENA =1;
ScibRegs.SCIHBAUD = 0x00;//0x0000; LSPCLK=90M/4=22.5M
ScibRegs.SCILBAUD = 0x92;//SCI_PRD; Baud = LSPCLK/(baud*8) = 22.5M/(0x0493 * 8) = 2400
ScibRegs.SCIPRI.all = 0x10;
ScibRegs.SCICTL1.all =0x0023; // Relinquish SCI from Reset
手册有提到
the SCIRXST register has two interrupt flag bits
(RXRDY and BRKDT), plus the RX ERROR interrupt flag which is a logical OR of the FE, OE, BRKDT,
and PE conditions.
RX ERROR interrupt不被使能，但是由于就收中断和BRKDT中断使能公用一个使能位ScibRegs.SCICTL2.bit.RXBKINTENA =1;所以
我在接收中断中有特殊处理 BRKDT位，如下
if(ScibRegs.SCIRXST.bit.BRKDT)
{
ScibRegs.SCICTL1.bit.SWRESET=0;
}
ScibRegs.SCICTL1.bit.SWRESET=1;
我的疑问是如果是其他的错误产生了，比如FE, OE, BRKDT,
and PE conditions.那么我上述的只是处理了BRKDT的条件软件复位，那么串口还能正常工作吗？会不会死在中断？
