81 / 228 page  µPD17072,17073 79 11.9 External (INT Pin) Interrupts 11.9.1 Outline of external interrupts Figure 11-9 outlines the external interrupts. As shown in this figure, an interrupt request for an external interrupt is issued at the rising or falling edge of the signal input to the INT pin. Whether the interrupt request is to be issued at the rising or falling edge of INT is specified independently through program. The INT pin is Schmitt trigger input pin to protect malfunctioning due to noise. This pin do not accept a pulse input that lasts for less than 100 ns. Figure 11-9. Outline of External Interrupt Remark INT: detects pin status IEG: selects interrupt edge 11.9.2 Edge Detection Block The edge detection block specifies the edge (rising or falling edge) of the input signal that issues the external interrupt request of the INT pin, and detects the specified edge. The edge is specified by IEG flag. Figure 11-10 shows the configuration and function of the interrupt edge select register. INT pin INT flag Schmitt trigger IEG flag Edge detection block IRQ flag Interrupt control block |
