Functional Description (continued)
10.0 SERIAL BUS
The serial bus interface consists of the sda (serial data), sclk
(serial clock) and sadr (device address select) pins. The KAC-
9627 can operate only as a slave.
The sclk pin is an input, it only and controls the serial interface,
all other clock functions within KAC-9627 use the master clock
10.4 Data Valid
The master must ensure that data is stable during the logic 1
state of the sclk pin. All transitions on the sda pin can only occur
when the logic level on the sclk pin is “0” as shown in Figure 33.

10.1 Start/Stop Conditions
The serial bus will recognize a logic 1 to logic 0 transition on the
sda pin while the sclk pin is at logic 1 as the start condition. A

logic 0 to logic 1 transition on the sda pin while the sclk pin is at

10.5 Byte Format
Every byte consists of 8 bits. Each byte transferred on the bus
must be followed by an Acknowledge . The most significant bit of
the byte is should always be transmitted first. See Figure 34.

10.6 Write Operation
A write operation is initiated by the master with a Start Condition
followed by the sensor ’s Device Address and Write bit. When

10.2 Device Address
The serial bus Device Address of the KAC-9627 is set to
1010101 when sadr is tied low and 0110011 when sadr is tied
high. The value for s adr is set at power up.
10.3 Acknowledgment
The KAC-9627 will hold the value of the sda pin to a logic 0 dur-
ing the logic 1 state of the Acknowledge clock pulse on sclk as
shown in Figure 32.
the master receives an Acknowledge from the sensor it can
transmit 8 bit internal register address. The sensor will respond
with a second Acknowledge signaling the master to transmit 8
write data bits. A third Acknowledge is issued by the sensor
when the data has been successfully received.
The write operation is completed when the master asserts a
Stop Condition or a second Start Condition . See Figure 35.
10.7 Read Operation
A read operation is initiated by the master with a Start Condition
followed by the sensor ’s Device Address and Write bit. When
the master receives an Acknowledge from the sensor it can
