Volume Adjustment Smoothing (VSEN)
1 = Volume changes smoothed by stepping through
intermediate values.
0 = Volume changes made by bypassing intermediate
settings.
Zero-Crossing Detection (ZDEN)
1 = Volume changes made only at zero crossings in the
audio waveform or after approximately 100ms.
0 = Volume changes made immediately upon request.
MAX9851: Speaker Output Mode (SPMODE)
00 = Speaker amplifiers shutdown.
01 = Right channel enabled only.
10 = Left channel enabled only.
11 = Stereo speaker output enabled.
MAX9853: Line Output Mode (LOMODE)
00 = Line outputs disabled and SHDNOUT high.
11 = Line outputs enabled and SHDNOUT low.
Headphone and Receiver Output Mode (HRMODE)
000 = Headphone and receiver amplifiers shutdown.
001 to 011 = Reserved.
100 = Stereo headphone mode.
101 = Single-ended mono headphone mode (L+R).
110 = Balanced mono headphone mode (bridge-tied
load output L+R).
111 = Receiver amplifier enabled (L+R).
HRMODE selects between headphone amplifier and
receiver amplifier modes. The headphone amplifier and
receiver amplifier cannot be enabled at the same time.
To minimize click/pop, HRMODE should be pro-
grammed after power-on sequence and AOK = 1 (reg-
ister 0x01, bit B7).
Transducer/Vibe Gain (TGAIN)
TGAIN selects the programmable-gain setting of the
VIBE signal data when signal conditioning is enabled.
Table 38 lists the gain setting for each code.
