________
INT0 to INT5 are external input interrupts. The level sense/edge sense switching bits of the interrupt control
register select the input signal level and edge at which the interrupt can be set to occur on input signal level
and input signal edge. The polarity bit selects the polarity.
With the external interrupt input edge sense, the interrupt can be set to occur on both rising and falling
edges by setting the INTi interrupt polarity switch bit of the interrupt request select register (address
031F
register to the falling edge (“0”).
When you select level sense, the INTi interrupt polarity switch bit of the interrupt request select register
(address 031F
Figure 9.9 shows the interrupt request select register.
