5.6 LED Interface/PHY Address Config
These five pins are latched into the RTL8201BL during power up reset to configure PHY address [0:4] used for MII
management register interface. And then, in normal operation after initial reset, they are used as driving pins for status
indication LED. The driving polarity, active low or active high, is determined by each latched status of the PHY address [4:0]
during power-up reset. If latched status is High then it will be active low, and if latched status is Low then it will be active high.
Refer to Section 7.5 for more information.

Type
I
Pin No.

Description
RESETB:
Set low to reset the chip. For a complete reset function, this pin
must be asserted low for at least 10ms.
Power Feedback Output:
Be sure to connect a 22uF tantalum capacitor for
frequency compensation and a 0.1uF capacitor for noise de-coupling. Then
connect this pin through a ferrite bead to PWFBIN(pin8). The connection
method is figured in section 7.11.
Power Feedback Input:
see the description of PWFBOUT.
