x = unknown, u = unchanged, - = unimplemented, q = value depends on condition.
Shaded cells are unimplemented, read as ‘0’.
Unimplemented in PIC18F2221/4221 devices; maintain these bits set.
See Register 23-14 for DEVID1 values. DEVID registers are read-only and cannot be programmed by the user.
Corrections are shown in bold. Where
possible, the original bold text formatting
has been removed for clarity.
