Silicon Errata Issues
1. Module: Low-Voltage In-Circuit Serial
DS80302F-page 4
Note:
If LVP (Low-Voltage Programming) mode is
enabled, programming the device using the V
pin while holding high or toggling the port pin RB3/
PGM during Program mode could disrupt the
programming sequence.
Work around
Pull down pin RB3/PGM using external circuitry
during programming of the device.

This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated by the shaded column in
the following tables apply to the current
silicon revision (A0 or A2, as applicable).

2. Module: MSSP (SPI Mode)
FIGURE 1:
EXAMPLE 1:
LOOP BTFSS SSPSTAT, BF
When the SPI is using Timer2/2 as the clock
source, a shorter than expected SCK pulse may
occur on the first bit of the transmitted/received
data (Figure 1).
Work around
To avoid producing the short pulse, turn off Timer2
and clear the TMR2 register, load the SSPBUF
with the data to transmit and then turn Timer2 back
on. Refer to Example 1 for sample code.
