Bypass Register
The Bypass Register consists of a single Shift Register stage. When the Bypass Register is
selected as path between TDI and TDO, the register is reset to 0 when leaving the Capture-DR
controller state. The Bypass Register can be used to shorten the scan chain on a system when
the other devices are to be tested.

Version
Version is a 4-bit number identifying the revision of the component. The JTAG version number
follows the revision of the device. Revision A is 0x0, revision B is 0x1 and so on. However, some
revisions deviate from this rule, and the relevant version number is shown in
Table 24-1.

Part Number
The part number is a 16-bit code identifying the component. The JTAG Part Number for
ATmega16A is listed in
Table 24-2.

Manufacturer ID
The Manufacturer ID is a 11 bit code identifying the manufacturer. The JTAG manufacturer ID
for ATMEL is listed in
Table 24-3.

Reset Register
The Reset Register is a Test Data Register used to reset the part. Since the AVR tri-states Port
Pins when reset, the Reset Register can also replace the function of the unimplemented optional
JTAG instruction HIGHZ.
A high value in the Reset Register corresponds to pulling the External Reset low. The part is
reset as long as there is a high value present in the Reset Register. Depending on the Fuse set-
tings for the clock options, the part will remain reset for a Reset Time-Out Period (refer to
8154B–AVR–07/09
