3.2.10 M e m o r y M a n a g e m e n t Unit Instructions
3.2.11 Multiprocessor Instructions
MOTOROLA
The TAS, CAS, and CAS2 instructions coordinate the operations of processors
The PFLUSH instructions flush the address translation caches (ATCs) and
can optionally select only nonglobal entries for flushing. PTEST performs a
search of the address translation tables, storing results in the MMU status
in multiprocessing systems. These instructions use read-modify-write bus
cycles to ensure uninterrupted updating of memory. Coprocessor instructions
control the coprocessor operations. Table 3-11 lists these instructions.
