Virtual PHY Reset (VPHY_RST)
Setting this bit resets the Virtual PHY. When the Virtual PHY is released from
reset, this bit is automatically cleared. All writes to this bit are ignored while
this bit is set.
Note:
Port 2 PHY Reset (PHY2_RST)
Setting this bit resets the Port 2 PHY. The internal logic automatically holds
the PHY reset for a minimum of 102uS. When the Port 2 PHY is released
from reset, this bit is automatically cleared. All writes to this bit are ignored
while this bit is set.
Note:
Port 1 PHY Reset (PHY1_RST)
Setting this bit resets the Port 1 PHY. The internal logic automatically holds
the PHY reset for a minimum of 102uS. When the Port 1 PHY is released
from reset, this bit is automatically cleared. All writes to this bit are ignored
while this bit is set.
Note:
Digital Reset (DIGITAL_RST)
Setting this bit resets the complete chip except the PLL, Virtual PHY, Port 1
PHY, and Port 2 PHY. The EEPROM Loader will automatically reload the
configuration following this reset, but will not reset the Virtual PHY, Port 1
PHY, or Port 2 PHY. If desired, the above PHY resets can be issued once
the device is configured. All system CSRs are reset except for any NASR
type bits. Any in progress EEPROM commands (including RELOAD) are
terminated.
When the chip is released from reset, this bit is automatically cleared. This
bit should be polled to determine when the reset is complete. All writes to
this bit are ignored while this bit is set.
Note:
Note:
Reset Control Register (RESET_CTL)
This register contains software controlled resets.
Note: This register can be read while the LAN9311/LAN9311i is in the reset or not ready states.
Note: Either half of this register can be read without the need to read the other half.
This bit is not accessible via the EEPROM Loader.
This bit is not accessible via the EEPROM Loader.
This bit is not accessible via the EEPROM Loader.
The LAN9311/LAN9311imust always be read at least once after
power-up or reset to ensure that write operations function properly.
This bit is not accessible via the EEPROM Loader.
