following portions of the PA to specify a secondary cache block and way:
- PA[Size of secondary cache - 2:Blocksize of secondary cache] is used to access the secondary cache.
- PA[0] is used to specify the way needed by Index operations.
Since PA[0] is used to indicate the way during CACHE Index operations, alignment errors are suppressed.
When accessing data in the secondary cache, PA[Blocksize-1:3] is also used to read or write a specific doubleword.
