5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Interrupt and Standby Status)
5.16 Interrupt and Standby Status
s Types of interrupts
Eight systems and 17 types of interrupts have been
provided for the S1C88816.
External interrupt
K00–K07 input interrupt (2 types)
K10 input interrupt (1 type)
Internal interrupt
Clock timer interrupt (4 types)
Stopwatch interrupt (3 types)
Programmable timer interrupt (2 types)
Serial interface interrupt (3 types)
Melody interrupt (1 type)
A/D converter interrupt (1 type)
An interrupt factor flag that indicates the genera-
tion of an interrupt factor and an interrupt enable
register that sets enable/disable for interrupt
requests have been provided for each interrupt
and interrupt generation can be optionally set for
each factor.
In addition, an interrupt priority register has been
provided for each system of interrupts and the
priority of interrupt processing can be set to 3
levels in each system.
Figure 5.16.1 shows the configuration of the
interrupt circuit.
Refer to the explanations of the respective periph-
eral circuits for details on each interrupt.
