The operation of the USART Transmit Interrupt
flag bit TXIF (PIR1<4>) is clarified as follows:
TXIF is not cleared immediately upon loading data
into the transmit buffer TXREG. The flag bit
becomes valid in the second instruction cycle fol-
lowing the load instruction (see Example 1). Poll-
ing TXIF immediately following a load of TXREG
will give invalid results (Example 2).
This clarification applies to all USART transmis-
sion modes (master or slave, synchronous or
asynchronous, 8-bit or 9-bit).
