controller state. The Bypass Register can be used to shorten the scan chain on a system when
the other devices are to be tested.

Figure 114. The Format of the Device Identification Register
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 x1 and so on.
The part number is a 16-bit code identifying the component. The JTAG Part Number for
ATmega32 is listed in
Table 87. AVR JTAG Part Number
The Manufacturer ID is a 11 bit code identifying the manufacturer. The JTAG manufacturer ID
for Atmel is listed in
Table 88. Manufacturer ID
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
