Register description
56.3.3 Device identification register
The device identification (JTAG ID) register, shown in the following figure, allows the
revision number, part number, manufacturer, and design center responsible for the design
of the part to be determined through the TAP. The device identification register is
selected for serial data transfer between TDI and TDO when the IDCODE instruction is
active. Entry into the Capture-DR state while the device identification register is selected
loads the IDCODE into the shift register to be shifted out on TDO in the Shift-DR state.
No action occurs in the Update-DR state.

Description
Part Revision Number. Contains the revision number of the part. Value is 0x0.
Design Center. Indicates the design center. Value is 0x2C.
Part Identification Number. Contains the part number of the device. Value is TBD.
Manufacturer Identity Code. Contains the reduced Joint Electron Device Engineering Council (JEDEC) ID.
Value is 0x00E .
IDCODE Register ID. Identifies this register as the device identification register and not the bypass
register. Always set to 1.
56.3.4 Boundary scan register
The boundary scan register is connected between TDI and TDO when the EXTEST,
SAMPLE or SAMPLE/PRELOAD instructions are active. It is used to capture input pin
data, force fixed values on output pins, and select a logic value and direction for
bidirectional pins. Each bit of the boundary scan register represents a separate boundary
