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.
