Interrupt request g

(level 1)

Interrupt request h

(level 1)       

Servicing of h

Interrupt request h is held pending even if interrupts are
enabled because its priority is the same as that of g.

Interrupt request f is held pending even if interrupts are
enabled because its priority is lower than that of e.

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.

Caution The values of EIPC and EIPSW must be saved before executing multiple interrupts.

Remarks 1.

a to u in the figure are the names of interrupt requests shown for the sake of explanation.

2.

The default priority in the figure indicates the relative priority between two interrupt requests.
