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.
