Figure 11.11
A key input interrupt request is generated by one of the input edges of pins K10 to K17. The key input interrupt can
be used as a key-on wake-up function to exit wait or stop mode.
The KIiEN bit (i = 0 to 7) in the KIEN register is be used to select whether or not the pins are used as the KIi input.
The KIiPL bit in the KIEN register is also be used to select the input polarity.
When inputting a low signal to the KIi pin, which sets the KIiPL bit to 0 (falling edge), the input to the other pins
K10 to K17 is not detected as interrupts. When inputting a high signal to the KIi pin, which sets the KIiPL bit to 1
(rising edge), the input to the other pins K10 to K17 is also not detected as interrupts.
Figure 11.11 shows a Block Diagram of Key Input Interrupt. Table 11.7 lists the Key Input Interrupt Pin
Configuration.
