Module: A/D
The A/D offset is greater than the specified limit in
Table 28-26 of the Device Data Sheet. The
updated conditions and limits are shown in bold
text in Table 1.
Work around
Three work arounds exist:
1. Configure the A/D to use the VREF+ and VREF-
pins for the voltage references. This is done by
setting the VCFG<1:0> bits (ADCON1<5:4>).
2. Perform a conversion on a known voltage
reference voltage and adjust the A/D result in
software.
3. Increase system clock speed and adjust A/D
settings accordingly. Higher system clock
frequencies decrease offset error.
Date Codes that pertain to this issue:
All engineering and production devices.

5.
Module: MSSP
I2C Receive mode should be enabled (i.e.,
RCEN bit should be set) only when the system is
idle (i.e., ACKEN, RCEN, PEN, RSEN and SEN all
equal zero). It should not be possible to set the
RCEN bit when the system is not idle; however,
the RCEN bit
can be set under this circumstance.
Work around
Wait for the system to become idle before setting
the RCEN bit. This requires a check for the
following bits to be clear: ACKEN, RCEN, PEN,
RSEN and SEN.

All engineering and production devices.
6.
Module: ECCP
When switching direction in Full-Bridge PWM
mode, the modulated outputs will switch immedi-
ately instead of waiting for the next PWM cycle.
This may generate unexpected short pulses on the
modulated outputs.
Work around
Disable the PWM or set duty cycle to zero prior to
switching directions.
