Figure 28-3. 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. Refer to the device data sheets to
find the correct number.
The Manufacturer ID is an 11-bit code identifying the manufacturer. For Atmel this code is
11x01F.
The Boundary-scan Chain has the capability of driving and observing the logic levels on all I/O
pins. Refer to
The PDICOM data register is a 9-bit wide register used for serial-to-parallel - and parallel-to-
serial conversion of data between the JTAG TAP and the PDI. For details refer to
”Program and Debug Interface” on page
The Boundary-scan chain has the capability of driving and observing the logic levels on the I/O
pins. To ensure a predictable chip behavior during and after the instructions EXTEST, CLAMP
and HIGHZ, the chip is automatically put in reset. During active reset, the external oscillators,
analog modules, and non-default port settings (like pull-up/down, bus-keeper, wired-AND/-OR)
are disabled. It should be noted that the current chip - and port state is unaffected by the SAM-
PLE and PRELOAD instructions.
Figure 28-4 on page 343
This cell is able to control and observe both pin direction and pin value via a two-stage Shift
Register. When no alternate port function is present, Output control corresponds to the DIR reg-
ister value, Output data corresponds to the OUT register value, and Input data corresponds to
the IN register value (tapped before the input inverter and - synchronizer). Mode represents
either an active CLAMP or EXTEST instruction, while ShiftDR is set when the TAP controller is
in its Shift-DR state.
