    MOTOROLA
    Features
    Table 1 shows the functionality supported by the members of the MPC866/859 family.

    Features
    The following list summarizes the key MPC866/859 features:
    Embedded single-issue, 32-bit PowerPC core (implementing the PowerPC architecture) with
    thirty-two 32-bit general-purpose registers (GPRs)
    — The core performs branch prediction with conditional prefetch, without conditional execution
    — 4- or 8-Kbyte data cache and 4- or 16-Kbyte instruction cache (see Table 1)
    – 16-Kbyte instruction cache (MPC866P and MPC859P) is four-way, set-associative with 256
    sets; 4-Kbyte instruction cache (MPC866T, MPC859T, and MPC859DSL) is two-way,
    set-associative with 128 sets.
    – 8-Kbyte data cache (MPC866P and MPC859P) is two-way, set-associative with 256 sets;
    4-Kbyte data cache(MPC866T, MPC859T, and MPC859DSL) is two-way, set-associative
    with 128 sets.
    – Cache coherency for both instruction and data caches is maintained on 128-bit (4-word)
    cache blocks
    – Caches are physically addressed, implement a least recently used (LRU) replacement
    algorithm, and are lockable on a cache block basis.
    — MMUs with 32-entry TLB, fully associative instruction and data TLBs
    — MMUs support multiple page sizes of 4, 16, and 512 Kbytes, and 8 Mbytes; 16 virtual address
    spaces and 16 protection groups.
    — Advanced on-chip-emulation debug mode
    The MPC866/859 provides enhanced ATM functionality over that of the MPC860SAR. The
    MPC866/859 adds major new features available in 'enhanced SAR' (ESAR) mode, including the
    following:
    — Improved operation, administration, and maintenance (OAM) support
    — OAM performance monitoring (PM) support
