680532 Busy tone continuous tone detection time
Busy tone signal state time tolerance for all ranges, and number of cycles required for
detection (a setting of 4 cycles means that ON-OFF-ON or OFF-ON-OFF must be
detected twice).
Tolerance (±)
Bit 1: 0, Bit 0: 0 = 75% Bits 2 and 3 must always be kept at 0.
680533
Bit 1: 0, Bit 0: 0 = 50% Bits 2 and 3 must always be kept at 0.
Bit 1: 0, Bit 0: 0 = 25%
Bit 1: 0, Bit 0: 0 = 12.5%
Bits 7, 6, 5, 4 - number of cycles required for cadence detection
