Description
JTAG TCK – Test Clock Signal pin
Clock signal from programmer to Target
Device JTAG port.
Ground Connection
Common ground connection between
Programmer and Target System.
JTAG TDO – Test Data Output pin
Data signal from Target device JTAG port
to programmer.
- Pins 4 + 7 are physically connected
inside the programmer.
- Connects to Vcc rail of Target System.
- Pin referred to as VTref on Atmel JTAG-
ICE.
JTAG TMS – Test Mode Select pin
Mode Select Signal from programmer to
Target Device JTAG port.
Microcontroller RESET control signal
This pin connects to the main RESET pin
of the Target Microcontroller. This pin is
not strictly needed for JTAG programming,
but it can be used to RESET the Target
Device before and after programming.
