* The fixed frequency clock (FFCLK) is internally
synchronized to the bus clock and must not exceed one half
of the bus clock frequency.

BUSCLK — The frequency of the bus is always half of ICSOUT.
ICSOUT — Primary output of the ICS and is twice the bus frequency.
ICSLCLK — Development tools can select this clock source to speed up BDC communications in
systems where the bus clock is configured to run at a very slow frequency.
ICSERCLK — External reference clock can be selected as the RTC clock source and as the
alternate clock for the ADC module.
ICSIRCLK — Internal reference clock can be selected as the RTC clock source.
ICSFFCLK — Fixed frequency clock can be selected as clock source for the TPM1, TPM2 and
MTIM modules.
LPOCLK — Independent 1-kHz clock source that can be selected as the clock source for the COP
and RTC modules.
TCLK — External input clock source for TPM1, TPM2 and MTIM and is referenced as TPMCLK
in TPM chapters.
