Interrupt clock On mode
Set this bit to 0 will disable the interrupt generate circuit clock, if the pin[n] interrupt is
disabled
1 = Interrupt generated circuit clock always enable
0 = Disable the clock if the GPIOA/B/C/D/E[n] interrupt is disabled
De-bounce counter clock source select
1 = De-bounce counter clock source is the internal 10 kHz clock
0 = De-bounce counter clock source is the HCLK
