Usage
Instruction Details
For details of the APSR see The Application Program Status Register (APSR) on page A2-14. Because of
the Do-Not-Modify nature of its reserved bits, the immediate form of MSR is normally only useful at the
Application level for writing to APSR_nzcvq (CPSR_f).
For the A and R profiles, MSR (immediate) on page B6-12 describes additional functionality that is available
using the reserved bits. This includes some deprecated functionality that is available in unprivileged and
privileged modes and therefore can be used at the Application level.
