10.3 Key Input Interrupt
A key input interrupt is generated on an input edge of any of the K1
be used as a key-on wakeup function to exit wait or stop mode. KIi input can be enabled or disabled
selecting with the KIiEN (i=0 to 3) bit in the KIEN register. The edge polarity can be rising edge or falling
edge selecting with the KIiPL bit in the KIEN register. Note, however, that while input on any KIi pin which
has had the KIiPL bit set to “0” (falling edge) is pulled low, inputs on all other pins of the port are not
detected as interrupts. Similarly, while input on any KIi pin which has had the KIiPL bit set to “1” (rising
edge) is pulled high, inputs on all other pins of the port are not detected as interrupts.
Figure 10.15 shows a block diagram of the key input interrupt.
