Table 9-45 PIDR1 register bit assignments
Reserved bit or field with Should-Be-Zero-or-Preserved (SBZP) behavior.
JEP106 identification code, bits[3:0]. Together, with PIDR4.DES_2 and PIDR2.DES_1, they indicate the designer of the component and not the implementer, except where the two are the same.
Part number, bits[11:8]. Taken together with PIDR0.PART_0 it indicates the component. The Part Number is selected by the designer of the component.
