7.2 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
come from either an external oscillator or from the on-chip PLL. (See
(CGM).)
7.2.1 Bus Timing
In user mode, the internal bus frequency is either the oscillator output (CGMXCLK) divided by four or the
divided PLL output (CGMPCLK) divided by four.
