5.7.2
Keyboard Interrupt (KBI) Module
The HCS08 has one KBI module with eight keyboard interrupt inputs that share port A pins.
The KBI module allows up to eight pins to act as additional interrupt sources. Four of these pins allow
falling-edge sensing while the other four can be configured for either rising-edge sensing or falling-edge
sensing. The sensing mode for all eight pins can also be modified to detect edges and levels instead of only
edges.
This on-chip peripheral module is called a keyboard interrupt (KBI) module because originally it was
designed to simplify the connection and use of row-column matrices of keyboard switches. However, these
inputs are also useful as extra external interrupt inputs and as an external means of waking up the MCU
from stop or wait low-power modes.
5.7.3
KBI Features
The keyboard interrupt (KBI) module features include:
Keyboard interrupts selectable on eight port pins:
— Four falling-edge/low-level sensitive
— Four falling-edge/low-level or rising-edge/high-level sensitive
— Choice of edge-only or edge-and-level sensitivity
— Common interrupt flag and interrupt enable control
— Capable of waking up the MCU from stop3 or wait mode
