DESCRIPTION
IS/O8
(PD)
In Internal PHY Mode, this pin can be configured
to display the respective internal MII signal.
TXD2
O8
(PD)
In External PHY Mode, this pin functions as the
transmit data 2 output to the external PHY.

TXD1
IS/O8/
OD8
(PU)
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output, or a Schmitt-triggered input.
IS
(PD)
IS/O8
(PD)
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
configuration straps.
In Internal PHY Mode, this pin can be configured
to display the respective internal MII signal.
TXD1
O8
(PD)
In External PHY Mode, this pin functions as the
transmit data 1 output to the external PHY.
GPIO5
RMT_WKP
IS/O8/
OD8
(PU)
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output or a Schmitt-triggered input.
IS
(PD)
This strap configures the default descriptor
values to support remote wakeup. This strap is
overridden by the EEPROM.
0 = Remote wakeup is not supported.
1 = Remote wakeup is supported.
See Note 2.1 for more information on
configuration straps.
