Access these registers individually or as a combination of any two or all three registers, using the register
name as an argument to the MSR or MRS instructions. For example:
read all of the registers using PSR with the MRS instruction
write to the APSR using APSR with the MSR instruction.
The PSR combinations and attributes are:

APSR and EPSR
1The processor ignores writes to the IPSR bits.
2Reads of the EPSR bits return zero, and the processor ignores writes to the these bits
See the instruction descriptions Section 3.10.6 (p. 83) and Section 3.10.7 (p. 83) for more
information about how to access the program status registers.
2.1.3.5.1 Application Program Status Register
The APSR contains the current state of the condition flags from previous instruction executions. See the
register summary in Table 2.2 (p. 7) for its attributes. The bit assignments are:
Table 2.4. APSR bit assignments
Bits
Name
Function
[31]
N
Negative or less than flag:
0 = operation result was positive, zero, greater than, or equal1 = operation result was negative or
less than.
[30]
Z
Zero flag:
0 = operation result was not zero1 = operation result was zero.
[29]
C
Carry or borrow flag:
0 = add operation did not result in a carry bit or subtract operation resulted in a borrow bit1 = add
operation resulted in a carry bit or subtract operation did not result in a borrow bit.
[28]
V
Overflow flag:
0 = operation did not result in an overflow1 = operation resulted in an overflow.
[27]
Q
Sticky saturation flag:
0 = indicates that saturation has not occurred since reset or since the bit was last cleared to zero1
= indicates when an SSAT or USAT instruction results in saturation.
This bit is cleared to zero by software using an MRS instruction.
