1.2 Target ISP Port – connector pin-out
The 'Target ISP Connector' port features all the signals required to implement In-System
Programming (ISP) of a Target IC using the SPI, JTAG, I2C or UART interface. This connector also
features the programmable "Target Vcc" and "Target Vpp" voltages plus a switched "EXTERNAL
Vcc" supply.
The illustration below shows the location of the 'Target ISP Connector' port on the rear panel of the
programmer.
The pin-out of this connector is detailed in the table below.

Target VCC
This pin should be connected to the
Target System Vcc.
Target External VCC
This pin should be connected to the
Target System Vcc.
Only use this pin if the "External

to.
I2C SCL clock signal
This is the I2C SCL clock signal.
I2C SDA data signal
This is the I2C SDA data signal.
Spare Output
This is a spare output pin. It is
designed to control the activation of
the relay coils on the Relay Board.
