(See
Reset (VPHY_RST)
When set, this bit resets all the Virtual PHY registers to their default state.
This bit is self clearing.
0: Normal Operation
1: Reset
Loopback (VPHY_LOOPBACK)
This bit enables/disables the loopback mode. When enabled, transmissions
from the external MAC are not sent to the switch fabric. Instead, they are
looped back onto the receive path.
0: Loopback mode disabled (normal operation)
1: Loopback mode enabled
Speed Select LSB (VPHY_SPEED_SEL_LSB)
This bit is used to set the speed of the Virtual PHY when the
Negotiation (VPHY_AN)
0: 10 Mbps
1: 100 Mbps
Auto-Negotiation (VPHY_AN)
This bit enables/disables Auto-Negotiation. When enabled, the
LSB (VPHY_SPEED_SEL_LSB)
are overridden.
0: Auto-Negotiation disabled
1: Auto-Negotiation enabled
Power Down (VPHY_PWR_DWN)
This bit is not used by the Virtual PHY and has no effect.
Isolate (VPHY_ISO)
This bit controls the MII input/output pins. When set and in PHY mode, the
MII output pins are not driven, MII pull-ups and pull-downs are disabled and
the input pins are ignored. When in MAC mode, this bit is ignored and has
no effect.
0: Non-Isolated (Normal operation)
1: Isolated
Restart Auto-Negotiation (VPHY_RST_AN)
When set, this bit updates the emulated Auto-Negotiation results.
0: Normal operation
1: Auto-Negotiation restarted
Virtual PHY Basic Control Register (VPHY_BASIC_CTRL)
This read/write register is used to configure the Virtual PHY.
Note: This register is re-written in its entirety by the EEPROM Loader following the release or reset
