4.1.1.2 External Pin Reset (RESET_N)

A hardware reset will occur when the RESET_N pin is asserted. Once the RESET_N input is deasserted, the LAN8650/1 will restart operation. The device will indicate to the station's controller that it has been reset and must be configured in the same way as if a Power-On Reset had occurred: the IRQ_N pin will be asserted and the RESETC (Reset Completed) bit of the OA_STATUS Register will be set to 1.

The RESET_N pin must be connected externally to VDDP if unused. If used, the RESET_N pin must be driven for a minimum period as defined in the RESET_N Timing section.
