#define HPI_TONEDETECTOR_THRESHOLD   HPI_CTL_ATTR(TONEDETECTOR, 1)

Set the threshold level of a tonedetector, Threshold is a -ve number in units of dB/100,.

#define HPI_TONEDETECTOR_STATE   HPI_CTL_ATTR(TONEDETECTOR, 2)

Get the current state of tonedetection The result is a bitmap of detected tones. pairs of bits represent the left and right channels, with left channel in LSB. The lowest frequency detector state is in the LSB

#define HPI_TONEDETECTOR_FREQUENCY   HPI_CTL_ATTR(TONEDETECTOR, 3)

Get the frequency of a tonedetector band.
