3.10.6 MRS
Move the contents of a special register to a general#purpose register.
3.10.6.1 Syntax
MRS{cond} Rd, spec_reg
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
Rd
is the destination register.
spec_reg
can be any of: APSR, IPSR, EPSR, IEPSR, IAPSR, EAPSR, PSR, MSP, PSP, PRIMASK,
BASEPRI
, BASEPRI_MAX, FAULTMASK, or CONTROL.
3.10.6.2 Operation
Use MRS in combination with MSR as part of a read#modify#write sequence for updating a PSR, for
example to clear the Q flag.
In process swap code, the programmers model state of the process being swapped out must be saved,
including relevant PSR contents. Similarly, the state of the process being swapped in must also be
restored. These operations use MRS in the state-saving instruction sequence and MSR in the state-
restoring instruction sequence.
Note
BASEPRI_MAX
is an alias of BASEPRI when used with the MRS instruction.
3.10.6.3 Restrictions
Rd
must not be SP and must not be PC.
3.10.6.4 Condition flags
This instruction does not change the flags.
3.10.6.5 Examples
MRS
R0, PRIMASK ; Read PRIMASK value and write it to R0
3.10.7 MSR
Move the contents of a general#purpose register into the specified special register.
3.10.7.1 Syntax
MSR{cond} spec_reg, Rn
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
