CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Interrupt and HALT)
4.16 Interrupt and HALT
The S1C60N13 Series provides the following interrupt settings, each of which is maskable.
External interrupt:
Input interrupt (two)
Internal interrupt:
Timer interrupt (three)
Stopwatch interrupt (two)
Serial interface interrupt (one)
To authorize interrupt, the interrupt flag must be set to "1" (EI) and the necessary related interrupt mask
registers must be set to "1" (enable).
When an interrupt occurs the interrupt flag is automatically reset to "0" (DI), and interrupts after that are
inhibited.
When a HALT instruction is input the CPU operating clock stops, and the CPU enters the HALT status.
The CPU is reactivated from the HALT status when an interrupt request occurs.
If reactivation is not caused by an interrupt request, initial reset by the watchdog timer causes reactivates
the CPU (when the watchdog timer is enabled).
Figure 4.16.1 shows the configuration of the interrupt circuit.
