Examples
Move the contents of a general-purpose register into the specified special register.

spec_reg
PRIMASK, BASEPRI, BASEPRI_MAX, FAULTMASK, or CONTROL.
The register access operation in MSR depends on the privilege level. Unprivileged software can
only access the APSR, see
ware can access all special registers.
In unprivileged software writes to unallocated or execution state bits in the PSR are ignored.
When you write to BASEPRI_MAX, the instruction writes to BASEPRI only if either:
See
Rn must not be SP and must not be PC.
This instruction updates the flags explicitly based on the value in Rn.
• Rn is non-zero and the current BASEPRI value is 0
• Rn is non-zero and less than the current BASEPRI value.
