7548 Group
Interrupts
The 7548 group interrupts are vector interrupts with a fixed
priority scheme, and generated by 12 sources: 4 external, 7
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
interrupt request bit and the interrupt enable bit. These bits and
the interrupt disable flag (I flag) control the acceptance of
interrupt requests. Figure 19 shows an interrupt control diagram.
An interrupt requests is accepted when all of the following
conditions 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.

Interrupt vector address and priority
NOTES:
1. Vector addressed contain internal jump destination addresses.
2. Reset function in the same way as an interrupt with the highest priority.
