4.3. State Transitions of the EZRadio Devices
Ready state is designed to give a fast transition time to TX or RX state with reasonable current consumption. In this
mode the crystal oscillator remains enabled reducing the time required to switch to TX or RX mode by eliminating
the crystal start-up time. An automatic sequencer will put the chip into RX or TX from any state. It is not necessary
to manually step through the states. Although it is not shown in the diagram, any of the lower power states can be
returned to automatically after RX or TX.
