The A/D offset is greater than the specified limit in
Table 26-24 of the Device Data Sheet. The
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

The BOR module may reset below the minimum
operating voltage of the device when configured
for BORV1:BORV0 = 11. The updated Reset
voltage specifications are shown in bold in
Table 3.

The EUSART auto-baud feature may periodically
measure the incoming baud rate incorrectly. The
rate of incorrect baud rate measurements will
depend on the frequency of the incoming
synchronization byte and the system clock
frequency.
Work around
None.

All engineering and production devices.
In Synchronous mode (SYNC = 1) with clock
polarity high (SCKP = 1), the EUSART transmits a
shorter than expected clock on the CK pin for bit 0.
