Description
IRQ0 Sense Control B
IRQ0 Sense Control A
00: Interrupt request generated at IRQ0 input low level
01: Interrupt request generated at falling edge of IRQ0
10: Interrupt request generated at rising edge of IRQ0
11: Interrupt request generated at both falling and
Cleared by reading IRQnF flag when IRQnF = 1,
then writing 0 to IRQnF flag
