Table 2 Configuration data word

The MSB bit should be loaded first into the configuration register.

Default configuration word: h8E08.1C20.2000.0000.00E7.0000.0000.E721.0F04.

5.2 ShockBurstTM configuration

The section B[119:16] contains the segments of the configuration register dedicated to

ShockBurstTM operational prot ocol. After VDD is turned on S hockBurstTM configuration is done

once and remains set whilst VDD is present, during operation only the first byte for frequency

channel and RX/TX switching need to be changed.
