Description
CPU interface clock tree power down enable.
=1, Enable
=0, Disable
Note: Power save a little bit when MII interface is used and
the traffic is stopped in the power management with normal
mode
Switch clock tree power down enable.
=1, Enable
=0, Disable
Note: Power save a little bit when MII interface is used and
the traffic is stopped in the power management with normal
mode
=00, LED0 -> Link/ACT, LED1-> Speed
=01, LED0 -> Link,
=10, LED0 -> Link/ACT, LED1 -> Duplex
=11, LED0 -> Link,
=1, The internal stretched energy signal from the analog
module will be negated and output to LED1 and the internal
device ready signal will be negated and output to LED0.
=0, The LED1/LED0 pins will indicate the regular LED
outputs.
(Note. This is for debugging purpose.)
=1, PLL power down enable
=0, Disable
Note: This bit is used in Energy Detect mode with pin 27
