instruction cache, both caches, or neither cache can be specified. When the data
cache is specified, the selected data cache lines are first pushed to memory (if they
contain dirty data) and then invalidated if the DPI bit of the CACR is cleared. Otherwise,
the selected data cache lines remain valid. Selected instruction cache lines are invali-
dated. The CACR is accessed via the MOVEC instruction.
Specific cache lines can be selected in three ways:
1. CPUSHL pushes and possibly invalidates the cache line (if any) matching the
2. CPUSHP pushes and possibly invalidates the cache lines (if any) matching the
3. CPUSHA pushes and possibly invalidates all cache entries.

physical memory page in the specified address register. For example, if 4K-byte
page sizes are selected and An contains $12345000, all cache lines matching
page $12345000 are selected.
