3. Module: RESET
 2003 Microchip Technology Inc.
Section 13.4.1 (“POWER-ON RESET (POR)”) has
been amended to clarify the minimum specifica-
tions required for MCLR in order to reset the
PIC16CXXX. The following paragraphs and figure
have been added:
If a MCLR pulse occurs that is less that the mini-
mum specification (parameter #30), improper
device operation can occur.
If the minimum specification cannot be met, then
an external circuit must be used to ensure that any
pulse width less than the specification will be
filtered before it reaches the MCLR pin.
A possible circuit to remedy this is shown in
Figure 6. This circuit works by delaying the MCLR
release following a power-up. If no delay is
required, the capacitor may be omitted.
An alternative would be to use a supervisory circuit
to control MCLR.
Design validation should be performed to verify
that the application works as expected.
