Chapter 5 Clock Distribution
Description
MCGOUTCLK divided by OUTDIV2 clocks the bus slaves
and peripheral (excluding memories)
MCGOUTCLK divided by OUTDIV3 clocks the external
FlexBus interface
MCGOUTCLK divided by OUTDIV4 clocks the flash memory
MCG output of the slow or fast internal reference clock
MCG output of the slow internal reference clock or a divided
MCG external reference clock. The MCGFFCLK is further
divided by 2 before being made available to modules outside
the MCG (as shown in the preceding figure).
MCG output of either IRC, MCGFLLCLK, MCGPLLCLK, or
MCG's external reference clock that sources the core,
system, bus, FlexBus, and flash clock. It is also an option for
the debug trace clock.
MCG output of the FLL. MCGFLLCLK or MCGPLLCLK may
clock some modules.
MCG output of the PLL. MCGFLLCLK or MCGPLLCLK may
clock some modules.
Input clock to the MCG sourced by the system oscillator
(OSCCLK) or RTC oscillator
System oscillator output of the internal oscillator or sourced
directly from EXTAL
System oscillator output sourced from OSCCLKthat may
clock some on-chip modules
System oscillator 32kHz output
Clock source for some modules that is chosen as
OSC32KCLK or the RTC clock
RTC oscillator output for the RTC module
PMC 1kHz output
