(7) Interrupt sequence
Interrupts only occur when the respective INTE flag, interrupt
enable bits (V10
V13, 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
occurs after 3 machine cycles only when the three interrupt
conditions are satisfied on execution of other than one-cycle
instructions (Refer to Figure 22).

Retaining level of system

is necessary.
Notes 1: The address is stacked to the last cycle.
2: This interval of cycles depends on the executed instruction at the time
when each interrupt activated condition is satisfied.
