PCA9672
Remote 8-bit I/O expander for Fm+ I2C-bus with interrupt and reset
7.1.1 Address map
7.2 Software Reset Call, and device ID addresses
Two other different addresses can be sent to the PCA9672.
General Call address: allows to reset the PCA9672 through the I2C-bus upon
reception of the right I2C-bus sequence. See Section 7.2.1 “Software Reset” for more
information.
Device ID address: allows to read ID information from the device (manufacturer, part
identification, revision). See Section 7.2.2 “Device ID (PCA9672 ID field)” for more
information.
