R = Read-only bit
P = Programmable bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state

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.
0000 0110 = PIC18F6490/8490 devices
0000 1011 = PIC18F6390/8390 devices
Note: 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.

R = Read-only bit
P = Programmable bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
