(7) Interrupt sequence
Interrupts only occur when the respective INTE flag, interrupt en-
able bits (V10–V13 and V20–V23), and interrupt request flag are
“1.” The interrupt actually occurs 2 to 3 machine cycles after the
cycle in which all three conditions are satisfied. The interrupt oc-
curs after 3 machine cycles only when the three interrupt condi-
tions are satisfied on execution of other than one-cycle instructions
(Refer to Figure 16).

(Notes 2, 3)
The program starts from
the interrupt address.

interrupts
Interrupt activated
condition is satisfied.
2: The address is stacked to the last cycle.
3: This interval of cycles depends on the executed instruction at the time when each interrupt activated condition is satisfied.
Notes 1: The 4513/4514 Group operates in the middle-speed mode after system is released from reset.
