Control and Output Status Signals
GPI0: General Purpose Input Zero. This signal is used during the device manufacturing process. It must
be grounded through a resistor in the device application board. The application board must allow the
flexibility of easily reworking this signal to a high level if device debug is necessary (by including an
uninstalled resistor to VDDO2).
GPI1: General Purpose Input One. This signal can be used to logically combine an external status
condition with LOSA or LOSB if enabled in an MDIO register. Note that if GPI1 is low, LOSA/B is asserted
if a logical combination in enabled. Similarly, if GPI1 is high, LOSA/B is de-asserted. If unused, this input
must be grounded in the device application (not floating).
