* 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 MCGOUT.
LPO — Independent 1-kHz clock that can be selected as the source for the COP and RTC modules.
MCGOUT — Primary output of the MCG and is twice the bus frequency.
MCGLCLK — Development tools can select this clock source to speed up BDC communications
in systems where BUSCLK is configured to run at a very slow frequency.
MCGERCLK — External reference clock can be selected as the RTC clock source. It can also be
used as the alternate clock for the ADC and MSCAN.
MCGIRCLK — Internal reference clock can be selected as the RTC clock source.
MCGFFCLK — Fixed frequency clock can be selected as clock source for the TPMx.
TPM1CLK — External input clock source for TPM1.
TPM2CLK — External input clock source for TPM2.
TPM3CLK — External input clock source for TPM3.
