Support summary

• Programming - NSDSP-1 with NSHVX or NSDSP-2
• Debugging provisions - No

ICSP Connection

Programming is impossible at voltages below 4.5V.

PIC16F610 can only be programmed with HVP (High Voltage Programming). This means it requires Vpp voltage (higher than Vdd) for programming.

NSDSP-2 generates Vpp internally and can program PIC16F610.

NSDSP-1 cannot generate Vpp. Therefore, to be programmed with NSDSP-1, PIC16F610 requires NSHVX High Voltage Extension or an external HVP circuit.

Since release 134, NSDSP software, when used with NSDSP-1, assumes that NSHVX is connected when programming PIC16F610. It manipulates the PGM/RTS pin (LVP, or pin 6 of ICSP header of NSDSP programmers) to control MCLR state through NSHVX. Even when NSHVX is not connected, NSDSP-1 will still tooggle PGM/RTS pin during programming.

Instead of NSHVX, you can use an external HVP circuit. Without NSHVX, PIC16F610 will be programmed correctly, but it may not reset after the programming, especially if MCLRE configuartion bit is ON. In such situation, it may be necessary to power-cycle the chip, or disconnect NSDSP and manually connect MCLR pin to the ground for a short moment to reset the PIC.

These considerations do not apply to NSDSP-2, which does not use PGM/RTS pin for HVP control.

Debugging

NSDSP cannot be used to debug PIC16F610.
