4. Module: Configuration Bits and Device IDs

Table 23-1: Configuration Bits and Device IDs, on

Page 253, has been changed to designate Bit 3 of

CONFIG4L as unimplemented.

The table is changed as shown.

Legend: x = unknown, u = unchanged, - = unimplemented, q = value depends on condition.

Shaded cells are unimplemented, read as ‘0’.

Note 1: Unimplemented in PIC18F2221/4221 devices; maintain these bits set.

2: See Register 23-14 for DEVID1 values. DEVID registers are read-only and cannot be programmed by the user.
