Write Data Format
There are three registers that configure the
MAX9765/MAX9766: the MUTE register, SHDN register,
and control register. In write data mode (R/W = 0), the
register address and data byte follow the device
address (Figure 7).
MUTE Register
The MUTE register (01hex) is a read/write register that
sets the MUTE status of the device. Bit 3 (MUTEL) of
the MUTE register controls the left channel, bit 4
(MUTER) controls the right channel. A logic high mutes
the respective channel, a logic low brings the channel
out of mute.
SHDN Register
The SHDN register (02hex) is a read/write register that
controls the power-up state of the device. A logic high
in bit 0 of the SHDN register shuts down the device; a
logic low turns on the device. A logic high is required in
bits 2 to 7 to reset all registers to their default register
settings.
Control Register
The control register (03hex) is a read/write register that
determines the device configuration. Bit 1 (IN1/IN2)
controls the input multiplexer, a logic high selects input
1, a logic low selects input 2. Bit 2 (HPS_EN) controls
the headphone sensing. A logic low configures the
device in automatic headphone detection mode. A
logic high disables the HPS input. Bit 3 (INT/EXT) con-
trols the microphone amplifier inputs. A logic low
selects differential (internal) input mode. A logic high
selects single-ended (external) input mode. Bit 4
(SPKR/HP) selects the amplifier operating mode when
