Table 9-45 PIDR1 register bit assignments
Bits | Reset value | Name | Function |
---|---|---|---|
[31:8] | 0x0 |
RES0 | Reserved bit or field with Should-Be-Zero-or-Preserved (SBZP) behavior. |
[7:4] | 0b1011 |
DES_0 | 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. |
[3:0] | 0b1001 |
PART_1 | 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. |
