The PIC16C54B (Rev. A Silicon ONLY) parts conform
functionally to the PIC16C5X Data Sheet (DS30453D),
except for the anomalies described below:
All the problems listed here will be addressed in future
revisions of the PIC16C54B silicon.

The minimum specification for the MCLR must be
met in order to RESET the PIC16C54B. If a MCLR
pulse occurs that is less that the minimum specifi-
cation (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 fil-
tered before it reaches the MCLR pin.
Work Around
A possible circuit is shown in Figure 1. Proper
design validation needs to be done to ensure
desired operation over the applications operating
conditions.
