System Clock Distribution
2
MC9S08FL16 series use ICS module as clock sources. The ICS module can use internal or external clock
source as reference to provide up to 20 MHz CPU clock. The output of ICS module includes,
The TCLK pin is an extra external clock source. When TCLK is enabled, it can provide alternate clock
source to TPMs and MTIM16. The on-chip 1 kHz clock provides clock source of COP module.

OSCOUT — XOSC output provides external reference clock to ADC.
ICSFFCLK — ICS fixed frequency clock reference (around 32.768 kHz) provides double of the
fixed lock signal to TPMs and MTIM16.
ICSOUT — ICS CPU clock provides double of the bus clock which is basic clock reference of
peripherals.
ICSLCLK — Alternate BDC clock provides debug signal to BDC module.
