JTAG Data Registers
Device Identification Register
Device specific ID codes
The following device specific registers can be selected as JTAG scan chain depending on the
instruction loaded in the JTAG Instruction Register. Additional registers exist, but are implicitly
described in the functional description of the relevant instructions.
The Device Identification Register contains a unique identifier for each product. The register is
selected by the IDCODE instruction, which is the default instruction after a JTAG reset.
The different device configurations have different JTAG ID codes, as shown in
Note that if the flash controller is statically reset, the ID code will be undefined
