LED Driver output 0
OP0: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161CI according to the Table A. The value is latched into the
DM9161CI registers at power-up/reset
LED Driver output 1
OP1: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of
the DM9161CI according to the Table A. The value is latched into the
DM9161CI registers at power-up/reset
LED Driver output 2
OP2: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161CI according to the Table A. The value is latched into the
DM9161CI registers at power-up/reset
Differential data is received from the media
Differential data is transmitted to the media in TP mode
PECL data is transmitted to the media in Fiber mode
Power Down Control
Asserted high to force the DM9161CI into power down mode. When in
power down mode, most of the DM9161CI circuit block’s power is
turned off, only the MII management interface (MDC, MDIO) logic is
available (the PHY should respond to management transactions and
should not generate spurious signals on the MII)). To leave power down
mode, the DM9161CI needs the hardware or software reset with the
PWRDWN pin low
Cable Status or Link Status
This pin is used to indicate the status of the cable connection when
power up reset latch low (Default)
0 = Without cable connection
1 = With cable connection
This pin is used to indicate the status of the Link connection when
power up reset latch high
HP Auto-MDIX Control
1: Disable auto mode
0: Enable HP Auto-MDIX mode
Not connect
0 = With link
1 = Without link
