FUNCTION
When set, enables P0.7 as a cause of a Keyboard Interrupt.
When set, enables P0.6 as a cause of a Keyboard Interrupt.
When set, enables P0.5 as a cause of a Keyboard Interrupt.
When set, enables P0.4 as a cause of a Keyboard Interrupt.
When set, enables P0.3 as a cause of a Keyboard Interrupt.
When set, enables P0.2 as a cause of a Keyboard Interrupt.
When set, enables P0.1 as a cause of a Keyboard Interrupt.
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.
