Keyboard Interrupt (S08KBIV2)
7.1 Introduction
The keyboard interrupt (KBI) module provides up to eight independently enabled external interrupt
sources.
7.1.1 KBI Clock Gating
The bus clock to the KBI can be gated on and off using the KBI bit in SCGC2. This bit is set after any
reset, which enables the bus clock to this module. To conserve power, this bit can be cleared to disable the
clock to this module when not in use. See
Section 5.7, Peripheral Clock Gating for details.
