7. Functional description
Refer to Figure 1 “Block diagram of PCA9625” .
7.1 Device addresses
Following a START condition, the bus master must output the address of the slave it is
accessing.
There are a maximum of 128 possible programmable addresses using the 7 hardware
address pins. Two of these addresses, Software Reset and LED All Call, cannot be used
because their default power-up state is ON, leaving a maximum of 126 addresses. Using
other reserved addresses, as well as any other Sub Call address, will reduce the total
number of possible addresses even further.
7.1.1 Regular I 2 C-bus slave address
The I 2 C-bus slave address of the PCA9625 is shown in Figure 3 . To conserve power, no
internal pull-up resistors are incorporated on the hardware selectable address pins and
they must be pulled HIGH or LOW.
Remark: Reserved I 2 C-bus addresses must be used with caution since they can interfere
with:
