This connector allows programming and debugging via AVR-JTAG or other
compatible tools.
TDI Input Test Data In. This is the serial data input for the shift register.
TDO OutputTest 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.
