Reserved. Leave unconnected.
Enable Debounce of STROBE signal
Pullup – Enabled
Pulldown - Disabled
Management interface operation mode:
000 – 16-bit parallel interface
001 – 8-bit parallel interface
010 – Serial with MII as Ethernet frame
transfer interface.
011 – Serial only. CPU can transmit/receive
frames with the serial interface.
111 – Unmanaged Serial. No CPU packet can
be transmit or received with the serial
interface. EEPROM can be used to configure
the device at bootup.
A one (1) indicates pullup. A zero (0)
indicates pulldown. TSTOUT[1] is the Least
Significant Bit (LSB).
Device ID. Default address of the device for
serial interface. Up to 8 device can be sharing
the serial management bus with different
device ID.
A one (1) indicates pullup. A zero (0)
indicates pulldown. TSTOUT[4] is the Least
Significant Bit (LSB).
EEPROM not installed.
Pullup: Not installed
Pulldown: Installed
Manufacturing Option. Must be pulled up.
Module Detect
Pullup: Enable. In this mode, the device will
detect the existence of a PHY (for hot swap
purpose).
Pulldown: Disable
