Serial Data Input
This is the serial data output pin
from the programmer. This pin
should be connected to the Serial
Data Input (SDI) pin on the Target
Microcontroller.
Not connected
SII (Serial Instruction Input)
This is the serial data input pin to
the programmer from the Target
Device. This pin should be
connected to the SII pin on the
Target Microcontroller.
Ground Connection
Common ground connection
between PROGRAMMER and
Target System.
SDO (Serial Data Output)
This is the serial data output signal
from the Target Device to the
programmer. It is an INPUT pin to
the programmer.
Ground Connection
Common ground connection
between PROGRAMMER and
Target System.
Target RESET control pin
This pin controls the Target Device
RESET pin. A +12.0V Vpp voltage
will be applied to this pin during
programming.
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.
