Keyboard Interrupt Module (KBI)
13.1 Introduction
The keyboard interrupt module (KBI) provides eight independently maskable external interrupts which are
accessible via PTA0–PTA7. When a port pin is enabled for keyboard interrupt function, an internal pull-up
device is also enabled on the pin.
13.2 Features
Features of the keyboard interrupt module include the following:
13.3 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
