KBF.7: Keyboard Line 7 flag
This is set by hardware when KBI7 detects a programmed level.
It generates a Keyboard interrupt request if KBE.7 is also set. It must be cleared by software.
KBF.6: Keyboard Line 6 flag
This is set by hardware when KBI6 detects a programmed level.
It generates a Keyboard interrupt request if KBE.6 is also set. It must be cleared by software.
KBF.5: Keyboard Line 5 flag
This is set by hardware when KBI5 detects a programmed level.
It generates a Keyboard interrupt request if KBE.5 is also set. It must be cleared by software.
KBF.4: Keyboard Line 4 flag
This is set by hardware when KBI4 detects a programmed level.
It generates a Keyboard interrupt request if KBE.4 is also set. It must be cleared by software.
KBF.3: Keyboard Line 3 flag
This is set by hardware when KBI3 detects a programmed level.
It generates a Keyboard interrupt request if KBE.3 is also set. It must be cleared by software.
KBF.2: Keyboard Line 2 flag
This is set by hardware when KBI2 detects a programmed level.
It generates a Keyboard interrupt request if KBE.2 is also set. It must be cleared by software.
KBF.1: Keyboard Line 1 flag
This is set by hardware when KBI1 detects a programmed level.
It generates a Keyboard interrupt request if KBE.1 is also set. It must be cleared by software.
KBF.0: Keyboard Line 0 flag
This is set by hardware when KBI0 detects a programmed level.
It generates a Keyboard interrupt request if KBE.0 is also set. It must be cleared by software.

KBDEN: Enable KBI de-bounce function. The default KBI function is enabled.
KBDEN = 0, enable KBI de-bounce function. The de-bounce time is selected by KBD [1:0].
KBDEN = 1, disable KBI de-bounce function. The KBI input pin without de-bounce mechanism.
KBD[1:0]: Select KBI de-bounce time. If KBDEN = “0”, the default de-bounce time is 320 ms.
KBD[1:0] = 00, the de-bounce time is 320 ms.
KBD[1:0] = 01, the de-bounce time is 160 ms.
KBD[1:0] = 10, the de-bounce time is 80 ms.
KBD[1:0] = 11, the de-bounce time is 40 ms.
