MDIX ENABLE: Default is to enable MDIX. This strapping option
disables Auto-MDIX. An external pull-down will disable Auto-
MDIX mode.
Energy Detect ENABLE: Default is to disable Energy Detect
mode. This strapping option enables Energy Detect mode for the
port. In Energy Detect mode, the device will initially be in a low-
power state until detecting activity on the wire. An external pull-up
will enable Energy Detect mode.
Clock to MAC Disable: This strapping option disables (floats) the
CLK2MAC pin. Default is to enable CLK2MAC output. An external
pullup will disable (float) the CLK2MAC pin. If the system does not
require the CLK2MAC signal, the CLK2MAC output should be dis-
abled via this strap option.
Extender Mode Enable: This strapping option enables Extender
Mode for both ports. When enabled, the strap will enable Single
Clock MII TX and RX modes unless RMII Mode is also strapped.
SNI Mode cannot be strapped if Extender Mode is strapped.
