Interrupt clock On mode
Set this bit “0” will disable the interrupt generate circuit clock, if the pin[n] interrupt is
disabled
0 = disable the clock if the P0/1/2/3/4[n] interrupt is disabled
1 = interrupt generated circuit clock always enable
n=0~7
De-bounce counter clock source select
1 = De-bounce counter clock source is the internal 10kHz clock
0 = De-bounce counter clock source is the HCLK
