Use the following sequence to read 16 bits of data from
a MAX11008 register (see Figure 3):
1) Drive CS low to select the device.
2) Send the appropriate read command byte (see
3) Receive 16 bits of data. The first 4 bits of data are
4) Drive CS high.

Connect SPI/I2C to DGND to select the I
I
and a serial clock line (SCL). The MAX11008 is I
patible within the DV
SCL facilitate bidirectional communication between the
MAX11008 and the master at rates up to 400kHz for fast
mode and up to 3.4MHz for high-speed mode (HS
mode). See the Bus Timing and HS I
for more information on data-rate configurations.
Figure 4 shows the 2-wire interface timing diagram. The
MAX11008 is a transmit/receive slave-only device, rely-
ing upon a master to generate a clock signal. The mas-
ter (typically a microcontroller) initiates data transfers
on the bus and generates the SCL signal to permit data
transfer.
