Keyboard Interrupt (S08KBIV2)
10.1 Introduction
The keyboard interrupt KBI module provides up to eight independently enabled external interrupt sources.
Only four (KBI1P0–KBI1P3) of the possible interrupts are implemented on the MC9S08QD4 series MCU.
These inputs are selected by the KBIPE bits.
Figure 10-1 Shows the MC9S08QD4 series with the KBI module and pins highlighted.
