Chapter 11 Internal Clock Source (S08ICSV2)
The CLKS bits can also be changed at anytime, but the RDIV bits must be changed simultaneously so that
the resulting frequency stays in the range of 31.25 kHz to 39.0625 kHz. The actual switch to the newly
selected clock will not occur until after a few full cycles of the new clock. If the newly selected clock is
not available, the previous clock will remain selected.
11.4.3
The BDIV bits can be changed at anytime and the actual switch to the new frequency will occur
immediately.
11.4.4
The low power bit (LP) is provided to allow the FLL to be disabled and thus conserve power when it is not
being used. However, in some applications it may be desirable to enable the FLL and allow it to lock for
maximum accuracy before switching to an FLL engaged mode. Do this by writing the LP bit to 0.
11.4.5
When IRCLKEN is set the internal reference clock signal will be presented as ICSIRCLK, which can be
used as an additional clock source. The ICSIRCLK frequency can be re-targeted by trimming the period
of the internal reference clock. This can be done by writing a new value to the TRIM bits in the ICSTRM
register. Writing a larger value will slow down the ICSIRCLK frequency, and writing a smaller value to
the ICSTRM register will speed up the ICSIRCLK frequency. The TRIM bits will effect the ICSOUT
frequency if the ICS is in FLL engaged internal (FEI), FLL bypassed internal (FBI), or FLL bypassed
internal low power (FBILP) mode. The TRIM and FTRIM value will not be affected by a reset.
Until ICSIRCLK is trimmed, programming low reference divider (RDIV) factors may result in ICSOUT
frequencies that exceed the maximum chip-level frequency and violate the chip-level clock timing
specifications (see the
If IREFSTEN is set and the IRCLKEN bit is written to 1, the internal reference clock will keep running
during stop mode in order to provide a fast recovery upon exiting stop.
All MCU devices are factory programmed with a trim value in a reserved memory location
(NVTRIM:NVFTRIM). This value can be copied to the ICSTRM register during reset initialization. The
factory trim value includes the FTRIM bit. For finer precision, the user can trim the internal oscillator in
the application to take in account small differences between the factory test setup and actual application
conditions.
11.4.6
The ICS module can support an external reference clock with frequencies between 31.25 kHz to 5 MHz
in all modes. When the ERCLKEN is set, the external reference clock signal will be presented as
ICSERCLK, which can be used as an additional clock source. When IREFS = 1, the external reference
clock will not be used by the FLL and will only be used as ICSERCLK. In these modes, the frequency can
be equal to the maximum frequency the chip-level timing specifications will support (see the
