In power-on reset phase, this pin will be latched by AX88780 to determine that system
operates in 32 or 16-bit mode. High state is 16-bit mode and low state is 32-bit mode.
The default is in 32-bit mode.
Upon finishing reset status, if bit11 of PHY_CTRL register is enabled, this pin stands
for:
Link: indicates a good link status, active low in 16-bit mode and active high in 32-bit
mode.
Traffic: indicates the traffic status and flashes while in TX or RX state.
If bit11 of PHY_CTRL is not enabled, this pin is as general-purpose pin and
controlled by GPIO_CTRL register.
In power-on reset phase, this pin will be latched by AX88780 to determine whether
AX88780 swaps the data or not. If the high state, AX88780 will sap the data. The
default is little-endian.
Upon finishing reset stage, if bit12 PHY_CTRL register is enabled, this pin stands for
speed mode. Low indicates PHY is in 10BASE-TX mode, and high state indicates
PHY in 100BASE-T mode.
This pin is tied to ground for normal operation.
