Description
In Internal PHY Mode, this pin can be configured
to display the respective internal MII signal. Refer
to the Internal MII Visibility Enable (IME) bit of the
Hardware Configuration Register (HW_CFG) on
page 125 for additional information.
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 programma-
ble as either a push-pull output, an open-drain
output, or a Schmitt-triggered input.
Swaps the mapping of HSIC_DATA and
HSIC_STROBE.
0 = The HSIC_DATA and HSIC_STROBE pin
functionality is not swapped.
1 = The HSIC_DATA and HSIC_STROBE pin
functionality is swapped.
See Note 2-1 for more information on configura-
tion straps.
In Internal PHY Mode, this pin can be configured
to display the respective internal MII signal. Refer

This General Purpose I/O pin is fully programma-
ble as either a push-pull output, an open-drain
output or a Schmitt-triggered input.
This strap configures the default descriptor values
to support remote wakeup. This strap is overrid-
den by the EEPROM.
0 = Remote wakeup is not supported.
1 = Remote wakeup is supported.
See Note 2-1 for more information on configura-
tion straps.
