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 87. JTAG Version Numbers
The part number is a 16-bit code identifying the component. The JTAG Part Number for
ATmega16 is listed in
Table 88. 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 89. 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
