PCA9535PWR - TI Function Overview

The PCA9535PWR is a remote 16-bit I²C and SMBus low-power I/O Expander with interrupt output and configuration registers. It provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface (serial clock (SCL), serial data (SDA)). The PCA9535 consists of two 8-bit configuration (input or output selection), input port, output port and polarity inversion (active-high or active-low operation) registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding input or output port register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master.
