In 16-Bit Asynchronous Counter mode (with or
without use of the Timer1 oscillator), the TMR1H
and TMR3H buffers do not update when TMRxL is
read.
This issue only affects reading the TMRxH regis-
ters. The timers increment and set the interrupt
flags as expected. The timer registers can also be
written as expected.
Work around
1. Use 8-bit mode by clearing the RD16 bit
2. Use the internal clock synchronization option

The MSSP configured in SPI slave mode will gener-
ate a write collision if SSPBUF is updated and the
previous SSPBUF contents have not been
transferred
Reinitializing the MSSP by clearing and setting the
SSPEN (SSPCON1<5>) bit prior to rewriting
SSPBUF will not prevent the error condition.
Work around
Prior to updating the SSPBUF register with a new
value, verify whether the previous contents were
transferred by reading the BF (SSPSTAT<0>) bit. If
the previous byte has not been transferred, update
SSPBUF and clear the WCOL (SSPCON1<7>) bit if
necessary.

All engineering and production devices.
In SPI mode, the SDO output may change after the
inactive clock edge of the bit ‘0’ output. This may
affect some SPI components that read data over
300 ns after the inactive edge of SCK.

unique system environments.
A test of a statistically significant sample of
pre-production systems, across the voltage and
current range of the application’s power supply,
should indicate if a system is susceptible to this
issue.
