KIN15 to KIN0 Interrupts, WUE15 to WUE8 Interrupts: Interrupts KIN15 to KIN0 and
WUE15 to WUE8 are requested by an input signal at pins KIN15 to KIN0 and WUE15 to WUE8.
Interrupts KIN15 to KIN0 and WUE15 to WUE8 have the following features:
• Interrupts KIN15 and KIN8, KIN7 to KIN0 and WUE15 to WUE8 each form a group. The
• Enabling or disabling of interrupt requests can be selected with the I bit in CCR.
• An interrupt is generated by a falling edge at pins KIN15 to KIN0 and WUE15 to WUE8.
• Enabling or disabling of interrupt requests KIN15 to KIN0 and WUE15 to WUE8 can be
• The status of interrupt requests KIN15 to KIN0 and WUE15 to WUE8 are not indicated.
The detection of KIN15 to KIN0 and WUE15 to WUE8 interrupts does not depend on whether the
relevant pin has been set for input or output. However, when a pin is used as an external interrupt
input pin, clear the corresponding port DDR to 0 so that it is not used as an I/O pin for another
function.
A block diagram of interrupts KIN15 to KIN0 and WUE15 to WUE8 is shown in figure 5.3.
