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
(except PTD6 and PTD7), an internal 30kΩ pullup device is also enabled
on the pin.
PTD6/KBI6/SCL–PTD7/KBI7/SDA pins do not have internal pullup
devices. These two pins are open-drain when configured as outputs.
User should connect pullup devices when using these two pins for KBI
function.
