H = 0 Identification-signal decoder synchronization with fH = 15.625 kHz; power ON
H = 1 Identification-signal decoder synchronization with 4 x fH (must be 1 for operation with
crystal or 4-MHz reference frequency)
Q = 0 PLL synchronization with line sync pulse; power ON
Q = 1 PLL synchronization with crystal oscillator (the bit for H must also be set to 1)
