short distances with a low power consumption. The Easy24-33 v6 development system features the MRF24J40MA ZigBee module.
Some of its key features are: 250kbps data rate, 2.4GHz operating frequency, ~20mA power consumption, open area range up to
400m, etc. Communication between the microcontroller and ZigBee module is performed through SPI interface. In order to enable
the operation of the ZigBee module, it is necessary to set switches 3, 4, 5 and 6 on the DIP switch SW4 to the ON position. It is also
necessary to enable SPI communication through the DIP switch SW3. Which of the switches on the DIP switch SW3 is to be used
depends on the arrangement of the following microcontroller pins RB8, RB12, RB11, RB14, RB10, RB9 and RB13. In Figure 13-3,
pins RB8, RB14 and RB9 are used for serial communication.
