A write to this register bit does not take effect until
any one of the following occurs:
• Software reset is asserted (register 0.15).
• Restart auto-negotiation is asserted (register
0.9).
• Power down (register 0.11, 16_0.2) transitions
from power down to normal operation.
• Copper link goes down.
After a hardware reset, this bit takes on the value of
pd_config_asm_pause_a.
1b = Asymmetric pause.
0b = No asymmetric pause.
A write to this register bit does not take effect until
any one of the following occurs:
• Software reset is asserted (register 0.15).
• Restart auto-negotiation is asserted (register
0.9).
• Power down (register 0.11, 16_0.2) transitions
from power down to normal operation.
• Copper link goes down.
After a hardware reset, this bit takes on the value of
pd_config_pause_a.
1b = MAC pause implemented.
0b = MAC pause not implemented.
0b = Not capable of 100BASE-T4.
A write to this register bit does not take effect until
any one of the following occurs:
• Software reset is asserted (register 0.15).
• Restart auto-negotiation is asserted (register
0.9).
• Power down (register 0.11, 16_0.2) transitions
from power down to normal operation.
• Copper link goes down.
If register 0.12 is set to 0b and speed is manually
forced to 1000 Mb/s in registers 0.13 and 0.6, then
auto-negotiation is still enabled and only 1000BASE-
T full-duplex is advertised if register 0.8 is set to 1b;
1000BASE-T half-duplex is advertised if 0.8 is set to
0b. Registers 4.8:5 and 9.9:8 are ignored.
Auto-negotiation is mandatory per IEEE for proper
operation in 1000BASE-T.
1b = Advertise.
0b = Not advertised.
