The Program Status Register (PSR) combines:
These registers are mutually exclusive bitfields in the 32-bit PSR.
Access these registers individually or as a combination of any two or all three registers, using the register name as an argu-
ment to the MSR or MRS instructions. For example:
The PSR combinations and attributes are:

• Application Program Status Register (APSR)
• Interrupt Program Status Register (IPSR)
• Execution Program Status Register (EPSR).
• read all of the registers using PSR with the MRS instruction
• write to the APSR N, Z, C, V and Q bits using APSR_nzcvq with the MSR instruction.
