Description
e _{CIDMD1.7 FSK on/off}
FSK on/off = 0: FSK receiver disabled; FSK on/off = 1: FSK receiver enabled
s CIDMD1.6 FSK-BOM-mask on/off FSK-BOM-mask on/off = 0: FSK interrupts will be generated when a data word was
received even before mark period (data from channel seizure);
t _{FSK-BOM-mask on/off = 1: FSK interrupts will only be generated after the mark}

ic _{CIDMD1.5 CAS on/off}
CAS on/off = 0: CAS detector disabled; CAS on/off = 1: CAS detector enabled
t ^{CIDMD1.4 POL on/off}
POL on/off = 0: disable interrupts due to polarity change;
POL on/off = 1: enable interrupts due to polarity change
e _{CIDMD1.3 INT polarity HIGH/LOW INT polarity HIGH/LOW = 0: interrupt pin active LOW;}
