Design Tips
Question 1:
Answer 1:
If the device you are using does not have filtering to the on-chip master clear circuit
ensure that proper external filtering is placed on the MCLR pin to remove narrow pulses. Electri-
cal Specification
Question 2:
Answer 2:
The most common reason for this is that the windowed device (JW) has not had its window cov-
ered. The background light causes the device to power-up in a different state than would typically
be seen in a device where no light is present. In most cases all the General Purpose RAM and
Special Function Registers were not initialized properly.
When my system is subjected to an environment with ESD and EMI, it oper-
ates erratically.
With JW (windowed) devices my system resets and operates properly. With
an OTP device, my system does not operate properly.
