Features
The system level clocks are provided by the MCG. The MCG consists of:
The clocks provided by the MCG are summarized as follows:
42
• Two individually trimable internal reference clocks (IRC), a slow IRC with a
• Frequency locked loop (FLL) using the slow IRC or an external source as the
• Phase locked loop (PLL) using an external source as the reference clock.
• Auto trim machine (ATM) to allow both of the IRCs to be trimmed to a custom
• MCGOUTCLK – this is the main system clock used to generate the core, bus, and
• MCGFLLCLK – this is the output of the FLL and is available any time the FLL is
