Design Tips
Question 1:
Answer 1:
Nothing. You probably code protected the device. If this is the case, the device is no longer
usable. See Subsection
Question 2:
Answer 2:
1.
2.
Question 3:
Answer 3:
That is by design. Also remember that Microchip does not recommend code protecting windowed
devices.
Did you re-assemble the source file specifying the PIC16C74A in the INCLUDE file and
LIST directives. The use of the CONFIG directive is highly recommended.
On the device programmer, did you specify the PIC16C74A, and were all the configuration
bits as desired?
I have a JW device and I can no longer program it (reads scrambled data or
all '0's). What’s wrong with the device?
In converting from a PIC16C74 to a PIC16C74A, my application no longer
works.
When I erase the device, the program memory is blank but the configura-
tion word is not yet erased.
