The Bypass Register consists of a single Shift Register stage. When the Bypass Regis-
ter 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.
Figure 114 shows the structure of the Device Identification Register.
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 0x1 and so on.
However, some revisions deviate from this rule, and the relevant version number is
shown in Table 87.
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.
Table 88. AVR JTAG Part Number
The Manufacturer ID is a 11 bit code identifying the manufacturer. The JTAG manufac-
turer ID for ATMEL is listed in Table 89.
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 settings for the clock options, the part will remain reset for a Reset Time-
Out Period (refer to “Clock Sources” on page 23) after releasing the Reset Register. The
