Figure 12. Enabling and polling interrupts
Individual interrupt sources
External interrupts Int0 and Int1
External interrupt inputs on pins EXTINT0 and EXTINT1 (pins 3.2 and 3.3) are either edge-
triggered or level-triggered, depending on bits IT0 and IT1 in the SFR named TCON.
When an external interrupt is generated from an edge-triggered (falling-edge) source, the
appropriate flag bit (IE0 or IE1) is automatically cleared by hardware upon entering the ISR.
When an external interrupt is generated from a level-triggered (low-level) source, the
appropriate flag bit (IE0 or IE1) is NOT automatically cleared by hardware.
