The “priority order” of Table 3.3 (1) shows the order of
the interrupt source to be acknowledge by the CPU when
more than one interrupt are requested simultaneously.
In interrupt of 4 and 5 orders are requested simultaneously,
for example, an interrupt of the “5th” priority is acknowledged
after a “4th” priority interrupt processing has been completed
by a RETI instruction. However, a lower priority interrupt can
be acknowledged immediately by executing an EI instruction
in a program that processes a higher priority interrupt.
The internal interrupt controller merely determines the priority
of the sources of interrupts to be acknowledged by the CPU
when more than one interrupt are requested at a time. It is,
therefore, unable to compare the priority of interrupt being
executed with the one being requested. To permit another
interrupt during a cetain iterrupt operation, set the interrupt
enabling flag for the source of the interrupt to be allowed, and
execute the EI command.
3.3.2 Micro DMA Processing
Figure 3.3 (3) is a flow chart of the micro DMA processing.
Parameters (addresses of source and destination, and transfer
mode) for the data transfer between memories are loaded by
the CPU from an address modified by an interrupt vector
value. After the data transfer between memories according to
these parameter, these parameters are updated and saved into
the original locations. The CPU then decrements the number of
transfers, and completes the micro DMA processing unless
the result is “0”.
If the number of transfer becomes “0”, the CPU proceeds
to the general-purpose interrupt processing described in
the previous item.
