Scrambling  
All formatted bits of a Mobitex Data Block are passed through a 9-bit scrambler. This scrambler is  
initialised at the beginning of the first Data Block in every Frame. The 511-bit sequence is generated  
with a 9-bit shift register with the output of the 5th and 9th stages XOR'ed and fed back to the input of  
the first stage. The scrambler is disabled during all other tasks, apart for TSO.
