1. Module: RESET
The minimum specification for the MCLR must be met
in order to reset the PIC16CXXX. If a MCLR pulse
occurs that is less than the minimum specification
(parameter #30), improper device operation can occur.
If the minimum specification cannot be met, then an
external circuit must be used to insure that any pulse
width, less than the specification, will be filtered before
it reaches the MCLR pin.

A possible circuit is shown in Figure 1. Proper design
validation needs to be done to ensure desired opera-
tion over the applications operating conditions.
