9. Module: RG5 Pin
RG5 will cause excess pin leakage whenever it
is driven low. When RG5 is held at 0V, the pin
will typically source an additional 160 µA of
current.
Work around
In power-sensitive applications, using RG5 as
an input, ensure that any input attached to this
pin Idles high.

10. Module: Primary Oscillator (XT Mode)
On some parts, using the XT oscillator at the top
end of its specified frequency range (3.0 -
4.0 MHz) may cause the part to cease driving
the oscillator.
Work around
Use XT mode only for frequencies lower than
3.0 MHz.
Use HS mode if frequencies greater than
3.0 MHz on a crystal oscillator are required.
