Programmer RXD (Transmit) pin
The programmer receives serial data on
this pin from the Target Device TXD
(Transmit) pin.
Target / Programmer GROUND
connection
Common ground connection between
PROGRAMMER and Target System.
Programmer ACTIVE LED
This pin can be driven LOW when a
programming action is taking place. The
signal can be used to illuminate an LED or
trigger an interrupt on the Target
Microcontroller.
Target / Programmer 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.
