MDI_MDIX_EN
Label
Type
Description
IPL/O MDI/MDI-X enable
MDI/MDI-X auto cross over
1: enable, 0:disable (default)
It is an input signal during reset and its value is latched at the end of reset to set
auto MDI/MDIX function. It is link LED of port 6 after reset if LED direct mode is
selected. It is internally pulled low.
IPH
Change capability enable
Force to be link at half duplex, if each node doesn’t support IEEE802.3x. This
will prevent the packet loss due to no flow control in full duplex mode.
1: enable (default), 0: disable
It is internally pulled high. It is connected to GND through a resistor to turn off
the function in IP178A application circuit.
IPH Savepw_a_en,
Power saving mode for fast link pulse
1: enable (default), 0:disable
It is internally pulled high. The default value must be adopted normal operation.

UTP_DET#
I
UTP detect enable
Power saving mode for unplugged port.
1: disable,
FLP is sent out every 12~16ms.
0: enable
FLP is sent out every 1.2 sec if cable is unplugged and the function is enabled.
If a FLP is received, IP178A resumes to send out FLP every 12~16ms.
This function is disabled in spite of the setting on this pin and it can be enable
by EEPROM only.
IPH
Far end fault detect function of Fiber port
1: enable (default), 0: disable
