ICSP connection

 

ICSP Connection

PIC24F16KL402 has more than one pair of PGECx and PGEDx pins. You can use any pair, but you must use them as a pair. For example, if PGEC2 is used for ICSPCLK, then ICSPDAT must be connected to PGED2.

All VSS and VDD pins must be connected. Even if one of these pins is not connected, programming may fail.

 

LVP Limitations

Since NSDSP is a Low-Voltage Programmer (LVP), it can only program PIC devices if MCLRE configuration bit is enabled. Fresh (unprogrammed) devices have MCLRE bit set and therefore they can be programmed. It is impossible to disable MCLRE bit during LVP programming, but if the device has been previously programmed with HVP programmer, the MCLRE 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.

 

Target Voltage below 3.0V

If voltage is less than 3.0V it is impossible to bulk erase the device. Unless the PIC device is code protected, NSDSP still can program the device, however, without the bulk erase it takes longer.

NSDSP cannot detect target voltage and it assumes that the voltage is above 3.0V. This ensures fast programming at usual voltages. However, if you want to program at voltages below 3.0V, you must specify the actual target voltage through programming software, or the programming will fail. If you specify the voltage below 3.0V NSDSP will apply special programming algorithm, which does not use bulk erase, but is slower than the regular algorithm.

If you are programming a device which is code protected, NSDSP cannot remove protection if the voltage is below 3.0V.

 

Debugging

NSDSP firmware contains all the necessary provisions for debugging PIC24F16KL402 with NSDS. Once NSDS support for this device is compliete, NSDS will be able to debug it.
