Silicon Errata Issues
1. Module: LCD
© 2009 Microchip Technology Inc.
Note:
The
waveforms when using type-B waveforms (WFT =
1) with one-third multiplex (LMUX<1:0> = 10).
Work around
Avoid the use of type-B waveforms with one-third
multiplex. When one-third is required, use type-A
waveforms.

2. Module: LP/Timer1 Oscillator Operation
1-2% of devices experience reduced drive as
temperatures approach -40°C. This will result in a
loss of Timer1 counts or stopped Timer1
oscillation.
This can also prevent Timer1 oscillator start-up
under cold conditions.
Work around
Use of low-power crystals properly matched to the
device will reduce the likelihood of failure. A 1MΩ
resister between OSC2 and V
improve the drive strength of the circuit.
