Reserved, must be cleared.
KBIx Interrupt Flag — KBF indicates when a KBIx interrupt is detected. Writes have no effect on KBF.
0 No KBIx interrupt detected.
1 KBIx interrupt detected.
KBIx Interrupt Acknowledge — Writing a 1 to KBACK is part of the flag clearing mechanism. KBACK always
reads as 0.
KBIx Interrupt Enable — KBIE determines whether a KBIx interrupt is requested.
0 KBIx interrupt request not enabled.
1 KBIx interrupt request enabled.
KBIx Detection Mode — KBIMOD (along with the KBIxES bits) controls the detection mode of the KBIx interrupt
pins.
0 KBIx pins detect edges only.
1 KBIx pins detect edges and levels.
KBIx Interrupt Pin Selects — Each of the KBIPEn bits enable the corresponding KBIx interrupt pin.
0 Pin not enabled as interrupt.
1 Pin enabled as interrupt.
