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.
