PHASE-LOCKED LOOP (PLL)
CGMRCLK
OSCILLATOR (OSC)
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.
Section 7. Clock Generator Module
In user mode, the internal bus frequency is either the crystal oscillator
output (CGMXCLK) divided by four or the PLL output (CGMVCLK)
divided by four.
When the power-on reset module or the low-voltage inhibit module
generates a reset, the clocks to the CPU and peripherals are inactive
