Figure 139. State Machine Sequence for Changing the Instruction Word
The AVR specific public JTAG instruction for setting the AVR device in the Reset mode or taking
the device out from the Reset Mode. The TAP controller is not reset by this instruction. The one
bit Reset Register is selected as Data Register. Note that the Reset will be active as long as
there is a logic “one” in the Reset Chain. The output from this chain is not latched.
The active states are:
The AVR specific public JTAG instruction for enabling programming via the JTAG port. The 16-
bit Programming Enable Register is selected as Data Register. The active states are the
following:
Shift-DR: The Reset Register is shifted by the TCK input.
Shift-DR: The programming enable signature is shifted into the Data Register.
Update-DR: The programming enable signature is compared to the correct value, and
Programming mode is entered if the signature is valid.
