When the SPI clock is configured for Timer2/2
(SSPCON1<3:0> = 0011), the first SPI high time
may be short.

HFINTOSC output frequency may have up to 1%
short term frequency instability.
Work around
Use the HS, XT or EC clock modes.

The internal oscillator module may experience a
±1% frequency shift after a Reset. The frequency
shift is not consistent and could cause the
oscillator
specification.
Work around
To minimize the chances of experiencing the
frequency shift, the following steps should be
taken:
Operate the internal oscillator at 8 MHz or 2
MHz.
Use an external pull-up on MCLR or use internal
MCLR mode.
Disable the Power Reset Timer (PWRT).

In Asynchronous Receive mode, the RCIDL bit of
the BAUDCON register will properly go low when
the RX input goes low at the leading edge of a Start
bit. If the RX input stays low for less than 1/8
bit time, then the Start bit is invalid and the RCIDL
should go high. However, the RCIDL bit will stay
low improperly until a valid Start bit is received.
Work around
When monitoring the RCIDL bit, measure the
length of time between the RCIDL going low and
the RCIF flag going high. If this time is greater than
one character time, then restore the RCIDL bit by
resetting the EUSART module. The EUSART
module is reset when the SPEN bit of the RCSTA
register is cleared.
Affected Silicon Revisions
5.2
The OERR flag of the RCSTA register is reset only
by clearing the CREN bit of the RCSTA register or
by a device Reset. Clearing the SPEN bit of the
RCSTA register does not clear the OERR flag.
Work around
Clear the OERR flag by clearing the CREN bit
instead of clearing the SPEN bit.
