—
When set, enables P0.6 as a cause of a Keyboard Interrupt.
KBI.5
—
When set, enables P0.5 as a cause of a Keyboard Interrupt.
KBI.4
—
When set, enables P0.4 as a cause of a Keyboard Interrupt.
KBI.3
—
When set, enables P0.3 as a cause of a Keyboard Interrupt.
KBI.2
—
When set, enables P0.2 as a cause of a Keyboard Interrupt.
KBI.1
—
When set, enables P0.1 as a cause of a Keyboard Interrupt.
KBI.0
—
When set, enables P0.0 as a cause of a Keyboard Interrupt.
Note: the Keyboard Interrupt must be enabled in order for the settings of the KBI register to be effective. The interrupt flag
(KBF) is located at bit 7 of AUXR1.
