86 / 277 page  R8C/14 Group, R8C/15 Group 11. Interrupt Rev.2.10 Jan 19, 2006 Page 74 of 253 REJ09B0164-0210 11.3 Key Input Interrupt A key input interrupt request is generated by one of the input edges of the K10 to K13 pins. The key input interrupt can be used as a key-on wake-up function to exit wait or stop mode. The KIiEN (i=0 to 3) bit in the KIEN register can select whether the pins are used as KIi input. The KIiPL bit in the KIEN register can select the input polarity. When inputting “L” to the KIi pin which sets the KIiPL bit to “0” (falling edge), the input of the other K10 to K13 pins are not detected as interrupts. Also, when inputting “H” to the KIi pin which sets the KIiPL bit to “1” (rising edge), the input of the other K10 to K13 pins are not detected as interrupts. Figure 11.17 shows a Block Diagram of Key Input Interrupt.
