Internal Clock Source (RS08ICSV1)
SC9RS08KA2 Series Data Sheet, Rev. 1

Freescale Semiconductor
9.1.1
Features
Key features of the ICS module are:
Frequency-locked loop (FLL) is trimmable for accuracy
— 0.2% resolution using internal 32 kHz reference
— 2% deviation over voltage and temperature using internal 32 kHz reference
— DCO output is 512 times internal reference frequency
Internal reference clock has 9 trim bits available
Internal reference clock can be selected as the clock source for the MCU
Whichever clock is selected as the source can be divided down
— 2 bit select for clock divider is provided (allowable dividers are: 1, 2, 4, and 8)
FLL engaged internal mode is automatically selected out of reset
9.1.2
Modes of Operation
There are four modes of operation for the ICS: FEI, FBI, FBILP, and stop.
9.1.2.1
FLL Engaged Internal (FEI)
In FLL engaged internal mode, which is the default mode, the ICS supplies a clock derived from the FLL
which is controlled by the internal reference clock.
9.1.2.2
FLL Bypassed Internal (FBI)
In FLL bypassed internal mode, the FLL is enabled and controlled by the internal reference clock, but is
bypassed. The ICS supplies a clock derived from the internal reference clock.
9.1.2.3
FLL Bypassed Internal Low Power (FBILP)
In FLL bypassed internal low power mode, the FLL is disabled and bypassed, and the ICS supplies a clock
derived from the internal reference clock.
9.1.2.4
Stop (STOP)
In stop mode, the FLL is disabled and the internal reference clocks can be selected to be enabled or
disabled. The ICS does not provide an MCU clock source.
9.1.3
Block Diagram
Figure 9-2 shows the ICS block diagram.
