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

or RC (when ADCS2:ADCS0 = 000 or x11), in
extremely rare cases, the E

31. Module: Brown-out Reset (BOR)
32. Module: MSSP
If either the HLVD or USB modules are enabled,
clearing the SBOREN bit (RCON<6>) when the soft-
ware
(BOREN1:BOREN0 = 01) may cause a Brown-out
Reset (BOR) event.
Work around
Before clearing the SBOREN bit, temporarily
disable the HLVD and USB modules.

When operated in I
baud rate may be somewhat slower than predicted
by the following formula:
Work around
If the target application is sensitive to the baud rate
and requires more precision, the SSPADD value
can be adjusted to compensate.
If this work around is going to be used, it is recom-
mended that the firmware first check the Revision
ID by reading the DEVID1 value at address
3FFFFEh. Silicon revisions B6 and B7 will match
