Type Aliases§

  • Field FLUSH reader - Write 1 to flush the cache. This clears the tag memory, but
    the data memory retains its contents. (This means cache-as-SRAM
    contents is not affected by flush or reset.)
    Reading will hold the bus (stall the processor) until the flush
    completes. Alternatively STAT can be polled until completion.
  • Field FLUSH writer - Write 1 to flush the cache. This clears the tag memory, but
    the data memory retains its contents. (This means cache-as-SRAM
    contents is not affected by flush or reset.)
    Reading will hold the bus (stall the processor) until the flush
    completes. Alternatively STAT can be polled until completion.
