15.2 SIM Bus Clock Control and Generation
The bus clock generator provides system clock signals for the CPU and peripherals on the MCU. The
system clocks are generated from an incoming clock, CGMOUT, as shown in
originates from either an external oscillator or from the internal clock generator.
15.2.1 Bus Timing
In user mode, the internal bus frequency is the internal clock generator output (CGMXCLK) divided by
four.
