Note2 : Procedures for using key inputs in dynamic pull-up mode
Note1: Procedures for using key inputs in static pull-up mode
A) When setting key inputs first after powering up the device
B) When modifying the active condition for a key input during operation
C) When enabling a key input during operation
A) When setting key inputs first after powering up the device
B) When modifying the active condition for a key input during operation
C) When enabling a key input during operation
1) Set KWUPCNT (PE = 1, DPE = 0).
2) Set the KWUPSTn<KEYnEN> corresponding to the key inputs to be used to 1.
3) Wait until the pull-up resistors are disabled.
4) Set the active conditions using the KWUPSTn corresponding to the key inputs to be used.
5) Clear the interrupt request using KWUPCLR.
6) Set the CG and INTC (refer to Section 3.4, “Interrupts” for details).
1) Disable key interrupts in the INTC (IMC1<18:16> = 000).
2) Modify the active condition for the key input using the corresponding KWUPSTn.
3) Clear the interrupt request using KWUPCLR.
4) Enable key interrupts in the INTC (set IMC1<18:16> to an appropriate level).
1) Disable key interrupts in the INTC (IMC1<18:16> = 000).
2) Set the KWUPSTn<KEYnEN> corresponding to the key input to be used to 1.
3) Wait until the pull-up resistors are disabled.
4) Set the active condition using the KWUPSTn corresponding to the key input to be used.
5) Clear the interrupt request using KWUPCLR.
6) Enable key interrupts in the INTC (set IMC1<18:16> to an appropriate level).
1) Set KWUPCNT (PE = 1, DPE = 0, TnSn = desired time).
2) Set the active conditions using the KWUPSTn corresponding to the key inputs to be used.
3) Clear the interrupt request using KWUPCLR.
4) Set the KWUPSTn<KEYnEN> corresponding to the key inputs to be used to 1.
5) Set the CG and INTC (refer to Section 3.4, “Interrupts” for details).
