(Debug modules are discussed separately; see Debug in Low Power Modes.) Numberratings (such as 4 MHz and 1 Mbps) represent the maximum frequencies or maximumdata rates per mode. Also, these terms are used:• FF = Full functionality. In VLPR and VLPW the system frequency is limited, but if amodule does not have a limitation in its functionality, it is still listed as FF.• Async operation = Fully functional with alternate clock source, provided the selectedclock source remains enabled• static = Module register states and associated memories are retained.• powered = Memory is powered to retain contents.• low power = Memory is powered to retain contents in a lower power state• OFF = Modules are powered off; module is in reset state upon wakeup. For clocks,OFF means disabled.• wakeup = Modules can serve as a wakeup source for the chip.Table 7-2.
