Function Details
Stops execution in low-power state until an interrupt occurs.
The cache line (or lines) is marked as invalid, so no cache hits occur in that line until it is re-allocated to an address.
Applies to write-back data caches. If the cache line contains stored data that has not yet been written out to the main mem-
ory, it is written to main memory immediately.
Stops the execution until all data in the write buffer has been stored in the main memory.
The memory cache line at the specified virtual address is loaded into the cache.
The operation carried out on a single cache line identifies the line using the data transferred in the MCR instruction.
The data is interpreted as using one of the two formats:
Below are the details of CP15 Register 7, or Cache Function Register, in MVA format.
• mva[31:5]: Modified Virtual Address
The non-defined bits should be zero when written and are unpredictable when read.
