Silicon Errata Issues

after a break.
After a wake-up due to a Break character,
the WUE bit is not automatically cleared.
Work around
Clear the WUE bit after waking up.
Fix
Rev. A5 Silicon and later revisions.
Affected Silicon Revisions
PIC16F687/PIC16F689/PIC16F690
The SPBRGH:SPBRG registers are not being
initialized correctly. If WUE and ABDEN are set at
the same time and a Break character followed by
a Sync character are received, then the
calculated baud rate will be random.
Work around
Set WUE and wait for the wake-up to occur.
Clear SPBRGH:SPBRG after waking up with the
break.
Set ABDEN to begin the auto-baud process.
Fix
Rev. A5 Silicon and later revisions.

allowed.
The SPBRGH:SPBRG are not initialized correctly
when ABDEN is set. This causes the measured
baud rate to be high by two counts.
Work around
Clearing the SPBRGH:SPBRG registers will
correctly initialize the baud rate counter. After the
auto-baud has been completed, the baud rate will
now be +1. The firmware should now subtract 1
from the Baud Rate Generator to produce the
correct baud rate.

After the auto-baud Sync character has been
received and the RCIF flag is set, there is
approximately 17 ms of
transmitter is enabled.
Work around
After the RCIF flag is set indicating the baud rate
has been measured, read the SPBRG register
and write the value back to SPBRG. This will
terminate the delay, and enable the transmitter
module.
