Interrupts
The 7544 Group interrupts are vector interrupts with a fixed prior-
ity scheme, and generated by 12 sources: 5 external, 6 internal,
and 1 software.
The interrupt sources, vector addresses(1) , and interrupt priority
are shown in Table 8.
Each interrupt except the BRK instruction interrupt has the inter-
rupt request bit and the interrupt enable bit. These bits and the
interrupt disable flag (I flag) control the acceptance of interrupt re-
quests. Fig. 17 shows an interrupt control diagram.
An interrupt request is accepted when all of the following condi-
tions are satisfied:
Interrupt disable flag.................................“0”
Interrupt request bit...................................“1”
Interrupt enable bit....................................“1”
Though the interrupt priority is determined by hardware, priority
processing can be performed by software using the above bits
and flag.
