Stereo indicator. 0 = no pilot signal detected; 1 = pilot signal detected.
ASI active. 0 = not active; 1 = ASI step is in progress.
AF update sample. 0 = LEV, USN and WAM information is taken from main frequency
(continuous mode); 1 = LEV, USN and WAM information is taken from alternative
frequency. Continuous mode during AF update and sampled mode after AF update.
Sampled mode reverts to continuous main frequency information after read.
Power-on reset. 0 = standard operation (valid I
reset detected since last read cycle (I

Reserved.
Identification. TEF6894H device type identification; ID[2:0] = 100.
Level. 8-bit value of level voltage from tuner; see Fig.4.
