In external PHY mode, this pin outputs the
management clock to the external PHY.
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output, or a Schmitt-triggered input.
In external PHY mode, this pin functions as the
transmit data 3 output to the external PHY.
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output, or a Schmitt-triggered input.
Note:
The EEP_SIZE strap selects the size of the
EEPROM attached to the device.
0 = 128 byte EEPROM is attached and a total of
seven address bits are used.
1 = 256/512 byte EEPROM is attached and a
total of nine address bits are used.
Note:
See
configuration straps.
In external PHY mode, this pin functions as the
transmit data 2 output to the external PHY.
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output, or a Schmitt-triggered input.
Swaps the mapping of USBDP and USBDM.
0 = USBDP maps to the USB D+ line and
USBDM maps to the USB D- line.
1 = USBDP maps to the USB D- line. USBDM
maps to the USB D+ line.
See
configuration straps.
Note 3.1
Note 3.1
(LAN9500A/LAN9500Ai ONLY):
GPIO7 may provide additional PHY Link
Up related functionality.
A 3-wire style 1K/2K/4K EEPROM that
is organized for 128 x 8-bit or 256/512 x
8-bit operation must be used.
