Special Control/Status Indications
Override AMDIX Strap
0 - AMDIX_EN (pin 73) enables or disables HP Auto MDIX
1 - Override pin 73. PHY Register 27.14 and 27.13 determine MDIX
function
Auto-MDIX Enable: Only effective when 27.15=1, otherwise ignored.
0 = Disable Auto-MDIX. 27.13 determines normal or reversed connection.
1 = Enable Auto-MDIX. 27.13 must be set to 0.
Auto-MDIX State. Only effective when 27.15=1, otherwise ignored.
When 27.14 = 0 (manually set MDIX state):
When 27.14 = 1 (automatic MDIX) this bit must be set to 0.
Do not use the combination 27.15=1, 27.14=1, 27.13=1.
Reserved: Write as 0. Ignore on read.
VCOOFF_LP: Forces the Receive PLL 10M to lock on the reference clock
at all times:
0 - Receive PLL 10M can lock on reference or line as needed (normal
1 - Receive PLL 10M is locked on the reference clock.
In this mode 10M data packets cannot be received.
Reserved: Write as 0. Ignore on read.
XPOL: Polarity state of the 10Base-T:
0 - Normal polarity
1 - Reversed polarity
Reserved: Read only - Writing to these bits have no effect.
Index (In Decimal):
operation)
0 = no crossover (TPO = output, TPI = input)
1 = crossover (TPO = input, TPI = output)
