tional Parameter A06A and updated conditions
and limits are shown in bold text in Table 2.
Work around
Three work arounds exist.
1. Configure the A/D to use the V

ing the setting of TXIF. This is because any
write to the TXSTA register results in a reset of
the baud rate timer which will effect any ongoing
transmission.
Work around
Load TX9D just after TXIF is set, either by polling
TXIF or by writing TX9D at the beginning of the
Interrupt Service Routine, or only write to TX9D
