10. DTP/External Interrupts
The DTP/external interrupt circuit is activated by the signal supplied to a DTP/external interrupt pin. The CPU
accepts the signal using the same procedure it uses for normal hardware interrupts and generates external
interrupts or activates the extended intelligent I/O service (EI2OS).
Features of DTP/External Interrupt :
Total 8 external interrupt channels.
Two request levels (“H” and “L”) are provided for the intelligent I/O service.
Four request levels (rising edge, falling edge, “H” level and “L” level) are provided for external interrupt requests.
