norm_point

disabled NDF + ss + offset value equal to active offset

 

 

 

 

 

 

NDF_enable

enabled NDF + ss + offset value in range of 0 to 782 or

 

 

 

enabled NDF + ss, if NDFPOR bit is set (Note that the

 

 

 

current pointer is not updated by an enabled NDF if the

inc_ind

disabled NDF + ss + majority of I bits inverted + no

 

 

 

majority of D bits inverted + previous NDF_enable, inc_ind

 

 

 

or dec_ind more than 3 frames ago
