1 = MAX9877A operational.
0 = MAX9877A in low-power shutdown mode.
SHDN is an active-low shutdown bit that overrides all
settings and places the entire device in low-power shut-
down mode. The I2C interface is fully active in this shut-
down mode and bypass mode remains operational. All
register settings are preserved while in shutdown.

Volume Control
The device has a separate volume control for left head-
phone, right headphone, and speaker amplifiers. The
total system gain is a combination of the input gain, the
volume control, and the output amplifier gain. Table 4
shows the volume settings for each volume control.
