Keyboard Interrupt (S08KBIV1)
9.1
The MC9S08AC16 Series has one KBI module with seven keyboard interrupt inputs that are shared with
port D and port G pins. See
hardware aspects of these pins.
9.2
The KBI input KBIP6 shares a common pin with PTD3 and AD11, and KBI input KBIP5 shares a common
pin with PTD2 and AD10.
The KBI inputs KBIP4–KBIP0 are shared on common pins with PTG4–PTG0.
KBIP3–KBIP0 are always falling-edge/low-level sensitive. KBIP6–KBIP4 can be configured for
rising-edge/high-level or for falling-edge/low-level sensitivity. When any of the inputs KBIP6–KBIP0 are
enabled and configured to detect rising edges/high levels, and the pin pullup is enabled through the
corresponding port pullup enable bit for that pin, a pulldown resistor rather than a pullup resistor is enabled
on the pin.
9.3
The keyboard interrupt (KBI) module features include:
