Data Synchronization Barrier.
where:
cond
DSB acts as a special data synchronization memory barrier. Instructions that come after the
DSB, in program order, do not execute until the DSB instruction completes. The DSB instruction
completes when all explicit memory accesses before it complete.
This instruction does not change the flags.
DSB{cond}
is an optional condition code, see
“Conditional execution” on page
84.
