6.15.2.2 Slow Clock Using an External Oscillator

For the best power consumption, the slow clock can be generated externally by an oscillator or sourced from elsewhere in the system. The external source must meet the requirements listed below. This clock must be fed into the CC330x pin Slow_CLK_IN and must be stable before nReset is deasserted and the device is enabled.
