PIC16F72 device has a noise filter in the MCLR Reset
path. The filter will detect and ignore small pulses.
It should be noted that a WDT Reset does not drive
MCLR pin low.
The behavior of the ESD protection on the MCLR pin
has been altered from previous devices of this family.
Voltages applied to the pin that exceed its specification
can result in both MCLR and excessive current beyond
the device specification during the ESD event. For this
reason, Microchip recommends that the MCLR pin no
longer be tied directly to V
RC network, as shown in Figure 11-5, is suggested.
