• Reset Register
• Boundary-scan Chain
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.
Figure 29-1. 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.
The part number is a 16-bit code identifying the component. The JTAG Part Number for
ATmega128RFA1 is listed in
The Manufacturer ID is a 11-bit code identifying the manufacturer. The JTAG
manufacturer ID for ATMEL is listed in
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 (see
output from this Data Register is not latched, so the reset will take place immediately,
