PRODUCTION DATA.
The clock signals from the Main PLL Controller are routed to various modules and peripherals on the device. Some modules and peripherals have one or more internal clock dividers. Other modules and peripherals have no internal clock dividers, but are grouped together and receive clock signals from a shared local clock divider. Internal and shared local clock dividers have fixed division ratios, as shown in Table 11-13.
