When either Timer1 or Timer3 is configured for
the
TxCON<1>(TMRxCS) = 0) and in the 8/16-Bit
Counter mode (TxCON<7>(RD16) = 0 or 1),
TMRxH and TMRxL will not increment on the
instruction that turns off the counter (TxCON<0>
(TMRxON) = 0).
Work around
None.

When either Timer1 or Timer3 is in the 8/16-Bit
Counter mode (TXCON<7> (RD16) = 0 or 1),
incrementing the prescale value (TxCON<5:4>
(TXCKPS<1:0>)) will take an additional count at
the previous value before the prescale value is
updated.
For example, changing the prescale value from
1:4 to 1:8 will occur four instruction cycles after
the execution of the instruction to update the
prescaler.
Work around
None.

7. Module: Enhanced Universal
In Synchronous Slave Transmission mode, the
TRMT bit (TXSTA<1> may not indicate when the
TSR register is empty.
Work around
Instead of polling the TRMT bit to determine the
status of the EUSART, poll the TXIF flag
(PIR1<4>) to determine when new data can be
written to the TXREG register.
