Address base. This 8-bit field is compared to address bits [31:24] from the processor's local
bus under control of the ACR address mask. If the address matches, the attributes for the
memory reference are sourced from the given ACR.
Address mask. This 8-bit field can mask any bit of the AB field comparison. If a bit in the
AM field is set, then the corresponding bit of the address field comparison is ignored.
ACR Enable. The EN bit defines the ACR enable. Hardware reset clears this bit, disabling
the ACR.
0 ACR disabled
1 ACR enabled
Supervisor mode. This two-bit field allows the given ACR to be applied to references based
on operating privilege mode of the ColdFire processor. The field uses the ACR for user
references only, supervisor references only, or all accesses.
00 Match if user mode
01 Match if supervisor mode
1x Match always—ignore user/supervisor mode
Reserved, should be cleared.
Cache mode. This bit defines the cache mode: 0 is cacheable, 1 is noncacheable.
0 Caching enabled
1 Caching disabled
