Since NSDSP is a Low-Voltage Programmer (LVP), it can only program PIC devices if LVP configuration bit is enabled. Fresh (unprogrammed) devices have LVP bit set and therefore they can be programmed. It is impossible to disable LVP bit during LVP programming, but if the device has been previously programmed with HVP programmer, the LVP bit may have been disabled.
When brown-out is enabled with BOREN configuration bit, LVP is only possible when the VDD voltage is above the brown-out threshold.
These limitations may be avoided with High-Voltage Programming (HVP), however NSDSP requires an external circuit for HVP.
We have measured time necessary to program and verify PIC10F320.
|Operation||Time||Programming and Verification||0.1s||Programming only||0.1s||Verification only||0.1s|
The measurements reflect the time necessary to program/verify the entire chip, including all user programmable memory areas.
NSDSP cannot be used to debug PIC10F320.
