TX Descriptor3 Occupied
Driver set this bit to ‘1’ to indicate that it had used TX descriptor3. When the
transmission is finished, AX88780 will auto-clear this bit.
TX Descriptor2 Occupied
Driver set this bit to ‘1’ to indicate that it had used TX descriptor2. When the
transmission is finished, AX88780 will auto-clear this bit.
TX Descriptor1 Occupied
Driver set this bit to ‘1’ to indicate that it had used TX descriptor1. When the
transmission is finished, AX88780 will auto-clear this bit.
TX Descriptor0 Occupied
Driver set this bit to ‘1’ to indicate that it had used TX descriptor0. When the
transmission is finished, AX88780 will auto-clear this bit.

Description
Reserved
Speed LED or GPIO1
When this bit is enabled, pin54 is as speed indicator, otherwise it is as
GPIO1 function and controlled by GPIO_CTRL register.
1= enable
0= disable
Link LED or GPIO0
When this bit is enabled, pin55 is as link/traffic indicator, otherwise it is
as GPIO0 function and controlled by GPIO_CTRL register.
1 = enable
0 = disable
EECS Pin as Full-Duplex LED
When this bit is enabled, EECS pin will be as full-duplex indicator and
EEDI pin will be as collision indicator.
1 = enable
0 = disable
Power down PHY
When this bit is enabled, AX88780 will power down internal PHY.
1 = enable
0 = disable
PHY Selection
When this bit is enabled, AX88780 will select internal PHY, otherwise it
will select external PHY.
1 = enable
0 = disable
Reserved
Internal 10/100M PHY operation mode
Driver can set these bits to control internal PHY operation mode.
3’b000 = auto-negotiation enable with all capability
3’b001 = auto-negotiation with 100BASE-TX FDX/HDX ability
3’b010 = auto-negotiation with 10BASE-T FDX/HDX ability
3’b011 = Reserved
3’b100 = Manual selection of 100BASE-TX FDX
