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 |
|
2 |
PROG_VCC |
P |
TARGET_VCC |

P |
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 |
PROG_RESET |
O |
RESET |
Target RESET control pin
This pin controls the Target Device RESET pin. It will be driven HIGH/LOW according to the device type and settings in the ‘Pre-program State Machine’ tab in the Eqtools project. |
|
6 |
PROG_GND |
P |
GROUND |
Ground Connection
Common ground connection between the programmer and Target System. |
