Device ID bits
These bits are used with the DEV<2:0> bits in the DEVID1 register to identify
part number.
Device ID bits
These bits are used with the DEV<10:3> bits in the DEVID2 register to identify
part number.
Revision ID bits
These bits are used to indicate the revision of the device. The REV4 bit is
sometimes used to fully specify the device type.
