1 TCK
2 GND
3 TDO
4 +5V
5 TMS
6 RESET
7 +5V
8 NC
9 TDI
10 GND
TDI Input Test Data In. This is the serial data input for the shift register.
TDO Output Test Data Out. This is the serial data output for the shift register. Data is shifted out of
the device on the negative edge of the TCK signal.
TMS Input Test Mode Select. The TMS pin selects the next state in the TAP state machine.
TCK Input Test Clock. This allows shifting of the data in, on the TMS and TDI pins. It is a
positive edge triggered clock with the TMS and TCK signals that define the internal
state of the device.
JTAG is used to to program and debug the MCU.
