1 |
PROG_VCC
|
P |
TARGET_VCC |
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. |

PROG_SPARE |
- |
No Connect |
Spare Programmer I/O pin
This pin is currently a I/O spare pin which is not used during SPI programming. In order to use this pin, the pin state must be setup in the EQTools tab |

PROG_TSCK2 |
O |
XTAL1 |
SCK2 Clock Output
This output pin is used to supply an external clock signal (SCK2) to the target microcontroller |
|
4 |
PROG_SDI |
O |
SDI |
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 |

Ground Connection
Common ground connection between PROGRAMMER and Target System |
|
8 |
PROG_SDO |
I |
SDO |
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 |
|

10 |
PROG_RESET/VPP |
O |
RESET |
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 |
