1. Assumes clock source is direct clock to EXTAL or crystal oscillator running 2-4MHz PLL must be enabled, locked, and

selected. The actual frequency depends on the source clock frequency and programming of the CGM module.

2. Master clock is derived from one of the following four sources:

fclk = fxtal when the source clock is the direct clock to EXAL

fclk = fpll when PLL is selected

fclk = fosc when the source clock is the crystal oscillator and PLL is not selected

fclk = fextal when the source clock is the direct clock to EXAL and PLL is not selected
