0b = Class B.
1b = Class A.
When set to disabled, 1000BASE-T is not
advertised even if registers 9.9 or 9.8 are set
to 1b.
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 defaults as
follows:
• ps_a1000_dis_s - bit 26_0.14 - 0, 0, 1, 1.
• When ps_a1000_dis_s transitions from
one to zero, this bit is set to 0b.
• When ps_a1000_dis_s transitions from
zero to one, this bit is set to 1b.
1b = Disable 1000BASE-T advertisement.
0b = Enable 1000BASE-T advertisement.
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 defaults as
follows:
• pd_rev_aneg_a - bit 26_0.13 - 0, 0, 1, 1.
• When pd_rev_aneg_a transitions from
one to zero this bit will be set to 0b.
• When pd_rev_aneg_a transitions from
zero to one this bit will be set to 1b.
1b = Reverse auto-negotiation.
0b = Normal auto-negotiation.
0b = Class B.
1b = Class A.
Reserved, write as 0x00.
0xb = Normal operation.
10b = Select 112 ns sequence.
11b = Select 16 ns sequence.
1b = Force negative polarity for receive only.
0b = Normal operation.
Reserved, write as 0x0.
