3. Module: External Memory Bus
DS80157D-page 2
When performing writes on the external memory
interface, a short glitch is present on the LB and
UB lines. The length of the glitch is proportional to
F
temperature. The glitch occurs well before the
WRH line is asserted and no adverse affect on the
operation of the external memory interface has
been observed.
Work around

4. Module: USART
Writing to the USART TXREGx, faster than the
baud rate in Synchronous mode, will overwrite the
previous value instead of double-buffering as in
Asynchronous mode.
Work around
Load the first character into TXREGx and then wait
for a TXx interrupt, or check the TXxIF bit before
writing each additional character to TXREGx.
