Rn
spec_reg can be any of: APSR, IPSR, EPSR, IEPSR, IAPSR, EAPSR, PSR, MSP, PSP, PRIMASK,
The register access operation in MSR depends on the privilege level. Unprivileged software can only
access the APSR, see Table 2.4 (p. 9) . Privileged software can access all special registers.
In unprivileged software writes to unallocated or execution state bits in the PSR are ignored.
Note
See Section 3.10.6 (p. 83) .
Rn must not be SP and must not be PC.
This instruction updates the flags explicitly based on the value in Rn.
MSR
No Operation.
NOP{cond}
where:
cond is an optional condition code, see Section 3.3.7 (p. 43) .
NOP does nothing. NOP is not necessarily a time#consuming NOP. The processor might remove it from
the pipeline before it reaches the execution stage.
Use NOP for padding, for example to place the following instruction on a 64#bit boundary.
This instruction does not change the flags.
CONTROL, R1 ; Read R1 value and write it to the CONTROL register
When you write to BASEPRI_MAX, the instruction writes to BASEPRI only if either:
• Rn is non-zero and the current BASEPRI value is 0
• Rn is non-zero and less than the current BASEPRI value.
is the source register.
BASEPRI, BASEPRI_MAX, FAULTMASK, or CONTROL.
