The APSR contains the current state of the condition flags from previous instruction executions.
• N: Negative Flag
0: operation result was positive, zero, greater than, or equal
1: operation result was negative or less than.
• Z: Zero Flag
0: operation result was not zero
1: operation result was zero.
• C: Carry or Borrow Flag
Carry or borrow flag:
0: add operation did not result in a carry bit or subtract operation resulted in a borrow bit
1: add operation resulted in a carry bit or subtract operation did not result in a borrow bit.
• V: Overflow Flag
0: operation did not result in an overflow
1: operation resulted in an overflow.
• Q: DSP Overflow and Saturation Flag
Sticky saturation flag:
0: indicates that saturation has not occurred since reset or since the bit was last cleared to zero
1: indicates when an
This bit is cleared to zero by software using an
