R/W = Read/Write, RO = Read only, SC = Self Clear, LL = Latched Low, LH = Latched High, LL and LH Clear
after read operation. Use default values of reserved bit(s) when writing to reserved bit(s).
DX LED Enable
Setting this bit enables FDX LED Mode. Bit 15 and 14 of this register are mutually exclusive. When FDX LED Mode is
enabled, TRANSMIT LED becomes FULL-DUPLEX LED and RECEIVE LED becomes ACTIVITY LED.
Interrupt Enable
Setting this bit enables Interrupt Mode. The state of this bit also affects which status signals are shifted out on the serial LED
data in serial LED mode.
Cable Disconnect Mask
When this bit is set to 1, the cable disconnect link change does not generate an interrupt.
FDX Mask
When this bit is set, changes in duplex mode does not generate an interrupt.
