Hi,
1.System: Wince
2.TL16CP754CI sent & receive data is right when my data is less than 20byte.
3.If my data is long than 20byte TL16CP754 will return SERIAL_IIR_RLS interrupt successive, It means RX_FIFO error.
Now read LSR=0x1110 0001,LSR[4:1] No error,LSR[7]=1(At least one parity error, framing error or break indication are stored in the receiver FIFO. Bit 7 is cleared when no errors are present in the FIFO.)
I need know why TL16CP754 enter the SERIAL_IIR_RLS interrupt, How to solve this issue, Thanks a lot!
SERIAL_IIR_RLS
