Description |
|
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 |
|
2 |
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 |
|
3 |
PROG_TSCK2 |
O |
XTAL1
Only connect this pin if you are using the SCK2 Clock Output to clock the Target Device during programming! |
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 tab. If the SCK2 oscillator is not being used, then the pin could be used as a spare output pin |
|
4 |
PROG_MOSI |
O |
MOSI
(except for ATmega103/128/64 – connect to RXD pin instead) |
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 |
|
5 |
N/C |

N/C |
Not connected |
|
6 |
PROG_MISO |
I |
MISO
(except for ATmega103/128/64 – connect to TXD pin instead) |
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 |
|
7 |
PROG_GND |
P |
GROUND |
Ground Connection
Common ground connection between the programmer and Target System |
|
8 |
PROG_SCK1 |
O |
SCK |
SPI Serial Clock Output
This is the SPI clock output signal used to clock data into / out of the Target Device |
|
9 |
PROG_GND |
P |
GROUND |
Ground Connection
Common ground connection between the programmer and Target System |
|
10 |
PROG_RESET/VPP |
O |
RESET |
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 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 |
