For receiving, a framing error with data of 00H can be assumed to be a break.
I met a problem, For example:
Break Header = 88 us
MAB = 8 us
With the quoted method,
for the first 80us, UART will detect 2 bytes of 0x00 with frame error.
80~84us of the break header will be taken as start bit of a new byte,
85~88us of the break header & MAB & some bits in start byte will form this new byte.
So this method will lead to wrong result.

Hope someone can help me.
If you don't understand my meaning , please let me know, I will add more comment.
Thanks in advance,
Vincent.
