The keyboard interrupt module (KBI) provides seven independently
maskable external interrupts which are accessible via PTA0–PTA6 pins.
Features of the keyboard interrupt module include the following:
•
•
•
•
Seven keyboard interrupt pins with separate keyboard interrupt
enable bits and one keyboard interrupt mask
Software configurable pull-up device if input pin is configured as
input port bit
Programmable edge-only or edge- and level- interrupt sensitivity
Exit from low-power modes
