SCK2 Clock Output (*Optional*)
This output signal can be used to
supply an external clock signal
(SCK2) to the target microcontroller.
This function must be enabled in the
EQTools <Pre-programming State
Machine> tab. If the SCK2 oscillator
is not being used, then the pin could
be used as a spare output pin.
Master Out Slave In
This is the SPI data output pin from
the programmer. This pin should be
connected to the MOSI pin on the
Target Microcontroller.
Not connected
Master In Slave Out
This is the SPI data input pin to the
programmer. This pin should be
connected to the MISO pin on the
Target Microcontroller.
Ground Connection
Common ground connection between
PROGRAMMER and Target System.
SPI Serial Clock Output
This is the SPI clock output signal
used to clock data into / out of the
Target Device.
Ground Connection
Common ground connection between
PROGRAMMER and Target System.
Target RESET control pin
This pin controls the Target Device
RESET pin. It will driven HIGH/LOW
according to the device type and
settings in the <Pre-program State
Machine> tab in the Eqtools project.
Warning!
During 'High Voltage Serial
Programming' of the Atmel
ATtiny11/12/15 microcontrollers, a
+12V Vpp voltage is generated by the
programmer on this pin.
