33.8 Core and Bus Independent Clocks for Peripherals

The following table lists the peripherals that can operate while the core, bus and peripheral clock frequencies are modified, thus providing communications at a bit rate which is independent for the core/bus/peripheral clock. This mode of operation is possible by using the internally generated independent clock sources.
