a larger assortment of clock configuration options. These registers control the following clock
functionality:
■ Source of clocks in sleep and deep-sleep modes
■ System clock derived from PLL or other clock source
■ Enabling/disabling of oscillators and PLL
■ Clock divisors
■ Crystal input selection
Important: Write the RCC register prior to writing the RCC2 register. If a subsequent write to the
RCC register is required, include another register access after writing the RCC register
and before writing the RCC2 register.
Figure 5-5 shows the logic for the main clock tree. The peripheral blocks are driven by the system
clock signal and can be individually enabled/disabled.
