memory operations is undefined). The state of the BSX bit in the PCSW has no effect on MMIO access by
modification of the destination register and the occurrence of side effects. If the LSB of rguard is 1, rdest is written and
the data cache status bits are updated if the addressed locations are cacheable. if the LSB of rguard is 0, rdest is not
changed and

Operation
r60 ← 0x84332211
no change, since guard is false
