1. SCI B of 28335, data stream is always on sending.
2. All things is OK when the CPU run without any breakpoint.
3. When set a break point, and break, run, break, run...,sometimes, the receiver will unavailable, it will not reach the break point added in the receive ISR.
4. The most important thing is，after reset the SCI B, using the SCI RST bit in the watch window of CCS, all things OK.
Why?
Thanks very much.
