    I/O Expander:
    · Enable the port as output and check voltage at test point TP10 .
    · Enable the port as input, apply voltage and check for valid data.
    · Probe on test points TP10, TP11, TP12,TP13 GPIO pins of I/O Expander.
    · I2C address:0100000
    ·

    Address / GPIO
    Remarks
