Figure 9-4 KBI x Pin Enable Register (KBIxPE)
KBIPEn — Keyboard Pin Enable for KBI Port Bit n (n = 7–0)
Each of these read/write bits selects whether the associated KBI port pin is enabled as a keyboard
interrupt input or functions as a general-purpose I/O pin.
1 = Bit n of KBI port enabled as a keyboard interrupt input
0 = Bit n of KBI port is a general-purpose I/O pin not associated with the KBI.
