bit 7-0 DEV<10:3>: Device ID bits
(1)
These bits are used with the DEV<2:0> bits in the Device ID Register 1 to identify the part number.
0001 0100 = PIC18F6722/8722 devices
0001 0011 = PIC18F6527/6622/6627/8527/8622/8627 devices
Note 1: These values for DEV<10:3> may be shared with other devices. The specific device is always identified by
using the entire DEV<10:0> bit sequence.
