4.2.2. MCU Mode
The SX1230 is also capable of operating in a conventional MCU controlled mode. Figure 4 shows the SX1230 operating in
MCU mode and connected to an external microcontroller. Note that CLKOUT provides the oscillator signal for the MCU,
thus negating the need for two crystal oscillators. The DCLK connection is also optional - only being required if the data
rate is to be determined by SX1230 or transmit filtering is to be used.
