Variation of IPL when Interrupt Request is Accepted
If an interrupt request is accepted, the interrupt priority level of the accepted interrupt is set in the IPL.
If an interrupt request, that does not have an interrupt priority level, is accepted, one of the values shown
in Table 1.10.6 is set in the IPL.

The indeterminate segment is dependent on the queue buffer.
If the queue buffer is ready to take an instruction, a read cycle occurs.

Time (a) is dependent on the instruction under execution. Thirty cycles is the maximum required for the
DIVX instruction (without wait).
Time (b) is as shown in Table 1.10.5.
________
Note 1: Add 2 cycles in the case of a DBC interrupt; add 1 cycle in the case either of an address match
interrupt or of a single-step interrupt.
Note 2: Locate an interrupt vector address in an even address, if possible.
