Internal Clock Source (S08ICSV1)
9.1
Introduction
The internal clock source (ICS) module provides clock source choices for the MCU. The module contains
a frequency-locked loop (FLL) as a clock source that is controllable by an internal reference clock. The
module can provide this FLL clock or the internal reference clock as a source for the MCU system clock,
ICSOUT.
Whichever clock source is chosen, ICSOUT is passed through a bus clock divider (BDIV) which allows a
lower final output clock frequency to be derived. ICSOUT is two times the bus frequency.
Figure 9-1
Shows the MC9S08QD4 series with the ICS module highlighted.
