PECR<PE0C> = “0”
PEFC1<PE0F> = “1”
PEPUP<PEE0> = “0”
PEIE<PIEE0> = “1”
Set KWUPST08＜KEY08EN＞ to “0” for the key input to be used.
Set KWUPST08<KEY082:KEY080> to “000” to define the active state of the key input to be
used.
Set KWUPST08＜KEY08EN＞ to “1” for the key input to be used.
Set KWUPCLR to “1010” to clear interrupt requests.
Set KWUPST08＜KEY08EN＞ to “1” for the key input to be used.
Program the CG and the INTC. (Refer to Chapter 6, “Interrupt Settings” for the details of
setting methods.)
Disable key interrupts by setting IMC04<IL122:120> to “000” at the INTC.
Set KWUPST08＜KEY08EN＞ to “0” for the key input to be used.
Change the active state by setting KWUPSTn for the key input to be changed.
Set KWUPST08＜KEY08EN＞ to “1” for the key input to be used.
Clear interrupt requests by setting KWUPCLR.
Enable key interrupts at the INTC. (Set IMC04<IL122:120> to a desired level.)
Disable key interrupts by setting IMC04<IL122:120> to “000” at the INTC.
Set KWUPST08＜KEY08EN＞ to “0” for the key input to be used.
Define the active state by setting KWUPSTn for the key input to be used.
Set KWUPST08＜KEY08EN＞ to “1” for the key input to be used.
Clear interrupt requests by setting KWUPCLR.
Set KWUPSTn＜KEYnEN＞ to “1” for the key input to be used.
Enable key interrupts at the INTC. (Set IMC04<IL122:120> to a desired level.)
