Design Tips
Question 1:
Answer 1:
If the MCLR pin does not rise fast enough, while the device’s voltage is in the valid operating
range, the internal Program Counter (PC) can increment. This means that the PC is no longer
pointing to the address that you expected to be at. The exact location depends on the number of
device clocks that occurred in the valid operating region of the device.
Question 2:
Answer 2:
The voltages / timings may be violated at the device. This could be due to the:
• Application board circuitry
• Cable length from programmer to target
• Large capacitance on V
When I try to do ICSP, the entire program is shifted (offset) in the device
program memory.
I am using a PRO MATE II with a socket that I designed to bring the pro-
gramming signal to my application board. Sometimes when I try to do ICSP,
the program memory is programmed wrong.
