3 . Description 
The GXA535 series is used to expand general-purpose input/output ports (GPIO). Port data is transmitted through the standard two-wire I2C protocol, which can support a maximum communication rate of 1MHz (up to 2MHz when high-speed mode is enabled).  
The GXA535 series has 16 bit push-pull GPIO ports that can directly drive LED components. Each bit of the GPIO port can be individually configured as an input or output mode, where power on is assumed to be the input mode.  
GXA555 has a built-in weak pull-up resistor that assigns a default high level to each GPIO port. GXA539 has a low effective reset input pin.
