The DP83867IRPAP PHY U37 LED interface is shown in This Figure. The DP83867IRPAP can be reset by the GEN3_EXP_RESET_B signal via the I2C0 TCA6416A U22 bus expander P06 pin 10 or the PS_POR_B signal generated by the MAX16025 U6 POR device pin 11. The SW3 pushbutton at the MAX16025 U6 pin 6 input also triggers a PS_POR_B signal.
