GAP_MODE
0
Defines the clock gapping mode of the demodulator
0: (default), the FS1 freq is controlled by stl-error (clock-pll mode) to align the instantaneous
value of the internal clock with respect to the received NICAM clock
1: the FS1 freq is fixed and the mean value of the internal clock is aligned by variable gapping
(src-error) with respect to the received NICAM clock
