Together, PIDR1.DES_0, PIDR2.DES_1, and PIDR4.DES_2 identify the designer of the component.


ARM. Bits[3:0] of the JEDEC JEP106 Identity Code.


Bits[11:8] of the 12-bit part number of the component. The designer of the component assigns this part number.


Indicates bits[11:8] of the part number of the component.
