Interrupt request b is acknowledged because the
priority of b is higher than that of a and interrupts are
enabled.
Although the priority of interrupt request d is higher
than that of c, d is held pending because interrupts
are disabled.
Interrupt request f is held pending even if interrupts are
enabled because its priority is lower than that of e.
Interrupt request h is held pending even if interrupts are
enabled because its priority is the same as that of g.
