Table 1 Table of configuration words

The configuration word is shifted in MSB first on positive CLK 1 edge, new configuration is enabled

on the falling edge of CS.

NOTE

On the falling edge of CS, the TRW-24G updates the number of bits actually shifted in during the

last configuration.

Example

If the TRW-24G is to be configured for 2 channel RX in ShockBurst TM, a total of 120 bits must be

shifted in during the first configuration after VDD is applied.

Once the wanted protocol, modus and RF channel are set, only one bit (RXE N) is shifted in to

switch between RX and TX.
