The module contains an IEEE 802.15.4 compliant RF transceiver, high speed oscillator, RC 
oscillator. The module is intended to running the Ember ZigBee software or other ZigBee 
network implementation, depending on the specific version.   
   
The application software together with the ZigBee protocol software stack can be programmed 
in Flash memory through SIF module, using an evaluation board from Ember InSight Desktop.   
   
To support user-defined applications, the module exposes the Ember Serial API over the SPI, 
which allows application development to occur on a Host microcontroller of choice. In addition 
to the four SPI signals, two additional signals, nHOST_INT and nWAKE, provide an easy-to-use 
handshake mechanism between the Host and the module. Also, an integrated voltage regulator, 
power-on-reset circuitry, sleep timer, and low-power sleep modes are available. The deep sleep
