Note:
SPSR, masking or unmasking the interrupts depending on the state saved in the
SPSR (the previous state of the ARM core).
The I bit in the SPSR is significant. If it is set, it indicates that the ARM core was just
about to mask IRQ interrupts when the mask instruction was interrupted. Hence, when
the SPSR is restored, the mask instruction is completed (IRQ is masked).
