Cautions on Use of Key Inputs With Pull-up Enabled
Cautions on Use of Key Inputs With Pull-up Disabled
B) To change the active state of a key input during operation
C) To enable a key input during operation
B) To change the active state of a key input during operation
C) To enable a key input during operation
A) When you make the first setting after turning the power ON
A) When you make the first setting after turning the power ON
1) Set PKPUP (<PKnUP>=“1”).
1) Make a setting of PKPUP (<PKnUP>=“1”)
2) Set KWUPSTn<KEYnEN> to "1" for the key input to be used.
3) Wait until the pull-up operation is completed.
4) Set KWUPSTn that corresponds to KEYn input to define the active state of the key input
5) Read KWUPST to clear interrupt requests.
6) Set CG and INTC (see chapter 6 for the procedure).
1) Disable key interrupts by setting IMC3<ILD2:D0> to "000" at the INTC.
2) Change the active state by setting KWUPSTn that corresponds to KEYn input to be
3) Clear interrupt requests by reading KWUPST.
4) Enable the key interrupt at the INTC. Set IMC3<ILD2:D0> to a desired level.
1) Disable key interrupts by setting IMC3<ILD2:D0> to "000" at the INTC.
2) Set KWUPSTn<KEYnEN> to "1" for the KEYn input to be used.
3) Wait until the pull-up operation is completed.
4) Set the active state by setting KWUPSTn that corresponds to KEYn input to be used.
5) Read KWUPST to clear interrupt requests.
6) Enable key interrupts at the INTC. (Set IMC3<ILD2:D0> to a desired level).
2) Set the active state by setting KWUPSTn that corresponds to KEYn input to be used.
3) Clear interrupt requests by reading KWUPST.
4) Set KWUPSTn<KEYnEN> to "1" for the KEYn input to be used.
5) Set CG and INTC (see chapter 6 for the procedure).
1) Disable key interrupts at the INTC (IMC3<ILD2:D0>=000).
2) Change the active state by setting KWUPSTn that corresponds to KEYn input to be
