A master reading data from the MAX9850 transmits the
proper slave address followed by a series of nine SCL
pulses. The MAX9850 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 (S) or REPEATED START (S
r
) con-
dition, a not acknowledge, and a STOP (P) condition.
SDA operates as both an input and an open-drain out-
put. A pullup resistor, typically greater than 500
, is
required on the SDA bus. SCL operates as an input only.
A pullup resistor, typically greater than 500
, 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 digital inputs of the
MAX9850 from high-voltage spikes on the bus lines, and
minimize crosstalk and undershoot of the bus signals.
Bit Transfer
One data bit is transferred during each SCL cycle. The
data on SDA must remain stable during the high period
of the SCL pulse. Changes in SDA while SCL is high
are control signals (see the
START and STOP
Conditions
section). SDA and SCL idle high when the
I

C bus is not busy.
