User manual
3.1.3 External Interrupt Mode register (EXTMODE - 0xE01F C148)
3.1.4 External Interrupt Polarity register (EXTPOLAR - 0xE01F C14C)
The bits in this register select whether each EINT pin is level- or edge-sensitive. Only pins
that are selected for the EINT function (see
VICIntEnable register
0xFFFF
course pins selected for other functions may cause interrupts from those functions).
Note: Software should only change a bit in this register when its interrupt is
disabled in VICIntEnable, and should write the corresponding 1 to EXTINT before
enabling (initializing) or re-enabling the interrupt. An extraneous interrupt(s) could
be set by changing the mode and not having the EXTINT cleared.
Table 26.
In level-sensitive mode, the bits in this register select whether the corresponding pin is
high- or low-active. In edge-sensitive mode, they select whether the pin is rising- or
falling-edge sensitive. Only pins that are selected for the EINT function (see
Section
Register (VICIntEnable - 0xFFFF
function (though of course pins selected for other functions may cause interrupts from
those functions).
Note: Software should only change a bit in this register when its interrupt is
disabled in VICIntEnable, and should write the corresponding 1 to EXTINT before
enabling (initializing) or re-enabling the interrupt. An extraneous interrupt(s) could
be set by changing the polarity and not having the EXTINT cleared.
