PCA9674/74A
Remote 8-bit I/O expander for Fm+ I2C-bus with interrupt
[1]
The PCA9674A does not acknowledge when AD2, AD1, AD0 follows this configuration.
7.2 Software Reset Call, and device ID addresses
Two other different addresses can be sent to the PCA9674/74A.
• General Call address: allows to reset the PCA9674/74A 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 (PCA9674/74A ID field)” for
more information.
