NSHVX Connectors

NSHVX has two 10-pin connectors. The one on the top, marked "NSDSP". matches the NSDSP connector, which consists of two parts - 6-pin ICSP and a 4-pin UART. The bottom connector, marked "PIC", impersonates NSDSP and can be connected everywhere where NSDSP could.

Pin No (left to right)	Name	NSDSP side	PIC side
1	MCLR	Driven by NSDSP to control MCLR voltage	Generated by NSHVX based on the signals on MCLR and LVP pins on the NSDSP side. May produce 9V voltage.
2	VDD	Connected through. Must be powered to support NSHVX operations. NSHVX may draw up to 30mA.
3	VSS	Connected through. Must be connected to the ground.
4	ICSPDAT	Connected through. Used in programming and debugging.
5	ICSPCLK	Connected through. Used in programming and debugging.
6	LVP	Driven by NSDSP to control MCLR voltage	Not connected
7	CTS	Connected through. Used in UART communications.
8	RX	Connected through. Used in UART communications.
9	TX	Connected through. Used in UART communications.
10	RTS	Connected through. Used in UART communications. In NSDSP programmers, this pin is internally connected to the LVP pin. Therefore, any attempt to drive this pin from the PIC side will disturb NSHVX operations and will cause programming failure.
