Keyboard Interrupt Module (KBI)
18.1 Introduction
The keyboard interrupt module (KBI) provides eight independently maskable external interrupts which are
accessible via PTD0–PTD7. When a port pin is enabled for keyboard interrupt function, an internal 30kΩ
pullup device is also enabled on the pin.
18.2 Features
Features of the keyboard interrupt module include the following:
18.3 I/O Pins
The eight keyboard interrupt pins are shared with standard port I/O pins. The full name of the KBI pins
are listed in
