19.10 Keyboard Module During Break Interrupts . . . . . . . . . . . . . . . 370
The keyboard interrupt module (KBI) provides eight independently
maskable external interrupts which are accessible via PTA0–PTA3 and
PTD4–PTD7. When a port pin is enabled for keyboard interrupt function,
an internal 30kΩ pullup device is also enabled on the pin.
