These values for DEV10:DEV3 may be shared with other devices. The specific device is always identified
by using the entire DEV10:DEV0 bit sequence.
DEV2:DEV0: Device ID bits
100 = PIC18F8390/8490
101 = PIC18F6390/6490
REV4:REV0: Revision ID bits
These bits are used to indicate the device revision.
DEV10:DEV3: Device ID bits
These bits are used with the DEV2:DEV0 bits in the Device ID Register 1 to identify the part number.
