34.2.10.6 MRS
Move the contents of a special register to a general-purpose register.
MRS{cond} Rd, spec_reg
where:
cond is an optional condition code, see
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.
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.
Remark: BASEPRI_MAX is an alias of BASEPRI when used with the MRS instruction.
See
Rd must not be SP and must not be PC.
This instruction does not change the flags.
