25.4.7.9 SEV
MSR updates one of the special registers with the value from the register specified by Rn.
See
In this instruction, Rn must not be SP and must not be PC.
This instruction updates the flags explicitly based on the value in Rn.
MSR CONTROL, R1 ; Read R1 value and write it to the CONTROL register
No Operation.
NOP
NOP performs no operation and is not guaranteed to be time consuming. The processor
might remove it from the pipeline before it reaches the execution stage.
Use NOP for padding, for example to place the subsequent instructions on a 64-bit
boundary.
There are no restrictions.
This instruction does not change the flags.
Send Event.
SEV
SEV causes an event to be signaled to all processors within a multiprocessor system. It
also sets the local event register, see
spec_reg is the special-purpose destination register: APSR, IPSR, EPSR, IEPSR,
IAPSR, EAPSR, PSR, MSP, PSP, PRIMASK, or CONTROL.
NOP ; No operation
