Bits [6:0] — BPVR6- BPVR0
Right Channel Audio Bypass Path Volume Control. These 7 bits control the gain setting of the right channel
bypass path volume control PGA. This volume control can be programmed from -35.5 dB to +12 dB in 0.5-dB
steps. Full volume (+12 dB) corresponds to a setting of 7Fh. Unity gain (0 dB) corresponds to 67h. Full
attenuation (-35.5 dB) corresponds to 20h. Any value lower than 20h engages the mute function described
above. The default volume setting is 0 dB.
BPVR[6:0] = 1100111 (103d) = 0 dB (default)
BPVR[6:0] = 1111111 (127d) = +12 dB (Max)
BPVR[6:0] = 0100000 (032d) = -35.5 dB (Min)
BPVR[6:0] = 0d-31d = mute
KEYCLICK CONTROL REGISTER (Page 2, Address 04H)
The Keyclick Control Register of the TSC2301 controls the setup of the internal keyclick sound generator. This
register is used to initiate and set the frequency, amplitude, and duration of the internally generated keyclick
sound. This register also controls the input to the differential mono output, and the soft-stepping function of the
TSC2301 volume controls.
The keyclick control register is formatted as follows:
Bit 15
