Date Codes that pertain to this issue:
All engineering and production devices.
When performing back-to-back transmission in
9-bit mode (TX9D bit in the TXSTAx register is
set), an ongoing transmission’s timing can be
corrupted if the TX9D bit (for the next trans-
mission) is not written immediately following the
setting of TXxIF. This is because any write to
the TXSTAx register results in a reset of the
Baud Rate Generator which will effect any
ongoing transmission.
Work around
Load TX9D just after TXxIF is set, either by polling
TXxIF or by writing TX9D at the beginning of the
Interrupt Service Routine, or only write to TX9D
when
