PICkit3 Debugger to target - max. cable length.

Dear Team,
We have planned to use customized cable (with proper mating connectors and 24AWG SC wire) between debugger and target board.
What is the maximum possible cable length allowed between PICkit 3 debugger and target board?

    This depends on the PIC you're debugging. Generally, couple feet may work Ok. However, it's best to keep it as short as possible to minimize noise - if debug session gets out of sync, it may never recover. Although some PICs, such as PIC24/dsPIC33 E/C have built-in debuggers with automatic re-synchronisaton capabilities.

    I posted on the other thread before I saw MBedders note.
    We have a design where the ICSP signals go 6 inches on the PCB to a connector with an 18 inch cable to a breakout board that has the PK3 header (plus SGMII and several JTAGs). Never had any issues.
    I normally try to keep the signals shorter, however.
