instruction loaded in the JTAG Instruction Register. Additional registers exist, but are implicitly
described in the functional description of the relevant instructions.
39.5.4.1 Device Identification Register
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.
Device specific ID codes
The different device configurations have different JTAG ID codes, as shown in Table 39-27.
Note that if the flash controller is statically reset, the ID code will be undefined
.
