^[a]The reset value is the value of the Main ID Register. ^[b]The reset value is the value of the Multiprocessor Affinity Register. ^[c]The reset value for bit[7] is UNK. ^[d]The reset value depends on the VFP and NEON configuration. If VFP and NEON are implemented, the reset value is `0x000033FF`. If VFP is implemented but NEON is not implemented, the reset value is `0x0000B3FF`. If VFP and NEON are not implemented, the reset value is `0x0000BFFF`. ^[e]The reset value for bits[55:48] is b00000000.
