Doc. No. 5014 Rev. A
The LED driver is interfaced through a 2-wire serial
I
2
C-bus in order to control the state and the current in
each of the six LED channels. The SDA and SCL lines
comply with the I
2
C electrical specification and should
be terminated with pull-up resistors. When the bus is
not used, both lines are high. The device supports the
maximum bus speed of 400 kbit/s. The serial bit
sequence is shown below for read and write
operations into the registers. Read and write
instructions are initiated by the master controller/CPU
and acknowledged by the slave LED driver. The I
2
C
address of the driver is internally fixed to the binary
value 1100110. The protocol requires that the start bit
and the device address are both repeated. For further
details on the I
2
C protocol, please refer to the I

C-Bus
Specification, document number 9398 393 40011,
from Philips Semiconductors.
