7.1.1 Regular I
7.1 Device addresses
Table 3.
[1]
Refer to
Following a START condition, the bus master must output the address of the slave it is
accessing.
There are a maximum of 4 possible programmable addresses using the 2 hardware
address pins for the 10-pin version and just one fixed address for the 8-pin version.
The I
internal pull-up resistors are incorporated on the hardware selectable address pins and
they must be pulled HIGH or LOW (10-pin versions only).
Remark: Using reserved I
devices are on the bus and/or the bus will be open to other I
date. In a closed system where the designer controls the address assignment these
addresses can be used since the PCA9632 treats them like any other address. The
LED All Call, Software Reset and PCA9564 or PCA9665 slave address (if on the bus) can
never be used for individual device addresses.
