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.
0101 0010 = PIC18F65K90, PIC18F66K90, PIC18F85K90 and PIC18F86K90
0101 0001 = PIC18F67K90 and PIC18F87K90
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.
