7547 Group
Interrupts
The 7547 Group interrupts are vector interrupts with a fixed prior-
ity scheme, and generated by 16 sources among 18 sources: 6
external, 11 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. 16 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.

Note 1: Vector addressed contain internal jump destination addresses.
2: Reset function in the same way as an interrupt with the highest priority.
3: Key-on wakeup interrupt and UART1 bus collision detection interrupt can be enabled by setting of interrupt source set register. The occurrence of
these interrupts are discriminated by interrupt source discrimination register.
4: A/D conversion interrupt and Timer 1 interrupt can be enabled by setting of interrupt source set register. The occurrence of these interrupts are dis-
criminated by interrupt source discrimination register.
