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).

8. Module: A/D (V
Note:
The operation of the module is clarified by the
addition of the following note to the end of
Section 18.1 (“A/D Acquisition Requirements”):
When using external voltage references
with the A/D converter, the source imped-
ance of the external voltage references
must be less than 20Ω to obtain the speci-
fied A/D resolution. Higher reference
source impedances will increase both off-
set and gain errors. Resistive voltage divid-
ers will not provide a sufficiently low source
impedance.
To maintain the best possible performance
in A/D conversions, external V
should be buffered with an operational
amplifier or other low output impedance
circuit.
