21. Module: MSSP (SPI Mode)
When the SPI is using Timer2/2 as the clock
source, a shorter than expected SCKx pulse may
occur on the first bit of the transmitted/received
data (Figure 1).
FIGURE 1:
SCKx PULSE VARIATION
USING TIMER2/2
Work around
To avoid producing the short pulse, turn off Timer2
and clear the TMR2 register, load the SSPxBUF
with the data to transmit and then turn Timer2 back
on. Refer to Example 4 for sample code.

AVOIDING THE INITIAL
SHORT SCK PULSE
22. Module: Timer1
In 16-bit Asynchronous Counter mode or 16-bit
Asynchronous Oscillator mode, the TMR1H and
TMR3H buffers do not update when TMRxL is
read. This issue only affects reading the TMRxH
registers. The timers increment and set the inter-
rupt flags as expected. The Timer registers can
also be written as expected.
Work around
Use 8-bit mode by clearing the RD16 (T1CON<7>)
bit or use the synchronization option by clearing
T1SYNC (T1CON<2>).
23. Module: PORTE
The RE4 pin latch remains at a logic level zero
when the ECCPMX Configuration bit is clear and
selects PORTH.
Work around
This issue will be corrected in a future revision of
silicon.
