Left and Right DAC Enable
(DACLEN/DACREN)
1 = Enable.
0 = Disable.
Enable and disable the DACs only when S1SDI and
S2SDI (register 0x03 and 0x05, bit B6) are cleared and
all soft-stop sequences have completed (indicated by
the SLD bit in resister 0x00) to insure proper click-and-
pop suppression. Disable DACLEN/DACREN before
making interface mode changes.
Left and Right ADC Enable (ADCLEN/ADCREN)
1 = Enable.
0 = Disable.
Disable ADCLEN/ADCREN before making interface
mode changes.
Transducer/Vibe DAC Enable (DATEN)
1 = Enable.
0 = Disable.
VIBE goes to high impedance when the DATEN is disabled.
Left and Right Microphone Enable
(MICLEN/MICREN)
1 = Enable.
0 = Disable.
I2C Serial Interface
The MAX9851/MAX9853 feature an I2C/SMBus-com-
patible, 2-wire serial interface consisting of a serial data
line (SDA) and a serial clock line (SCL). SDA and SCL
facilitate communication between the MAX9851/
MAX9853 and the master at clock rates up to 400kHz.
Figure 10 shows the 2-wire interface timing diagram.
The master generates SCL and initiates data transfer
on the bus. A master device writes data to the
MAX9851/MAX9853 by transmitting the proper slave
address followed by the register address and then the
data word. Each transmit sequence is framed by a
START (S) or REPEATED START (Sr) condition and a
STOP (P) condition. Each word transmitted to the
MAX9851/MAX9853 is 8 bits long and is followed by an
acknowledge clock pulse. A master reading data from
the MAX9851/MAX9853 transmits the proper slave
address followed by a series of nine SCL pulses. The
MAX9851/MAX9853 transmits data on SDA in sync with
the master-generated SCL pulses. The master acknowl-
edges receipt of each byte of data. Each read
sequence is framed by a START or REPEATED START
condition, a not acknowledge, and a STOP condition.
SDA operates as both an input and an open-drain out-
put. A pullup resistor, typically greater than 500
Ω, is
required on the SDA bus. SCL operates as only an
input. A pullup resistor, typically greater than 500
Ω, is
required on SCL if there are multiple masters on the
bus, or if the master in a single-master system has an
open-drain SCL output. Series resistors in line with SDA
and SCL are optional. Series resistors protect the digi-
tal inputs of the MAX9851/MAX9853 from high-voltage
spikes on the bus lines, and minimize crosstalk and
undershoot of the bus signals.
