3.5 Equinox 10-way Header (Generic SPI Interface)
This connection method is suitable for interfacing the programmer to a Target System which features
the following:
This is the favoured ISP connector as it allows the following additional functions:
To implement this connection, simply plug the 10-way ISP cable into the header marked ‘Equinox’
and plug the other end of the cable into the matching header on the Target System.

Description
Target VCC
This pin should be connected to the
Target System Vcc. This voltage
could be used to power the
programmer depending on the
settings of the power switch/jumper
on the programmer.
Spare Programmer I/O pin
This pin is currently a spare I/O pin
which is not used during SPI
programming. In order to use this pin,
the pin state must be setup in the
EQTools <Pre-programming State
Machine> tab.
