Soft Reset (SRST)
A soft reset is performed by setting the SRST bit of the
A soft reset will reset the HBI, Host MAC, and System CSRs below address 100h. The soft reset also
clears any TX or RX errors in the Host MAC transmitter and receiver (TXE/RXE). This reset does not
latch the configuration straps. On soft reset, the EEPROM Loader is run, but loads only the MAC
address into the Host MAC. No other values are loaded by the EEPROM Loader in this case.
A soft reset typically takes 590uS, plus an additional time (550uS for I
data is loaded from the EEPROM via the EEPROM Loader.
Single-Module Resets
A single-module reset will reset only the specified module. Single-module resets do not latch the
configuration straps or initiate the EEPROM Loader. A single-module reset is initiated by assertion of
the following:
Port 2 PHY Reset
A Port 2 PHY reset is performed by setting the PHY2_RST bit of the
(RESET_CTL)
Upon completion of the Port 2 PHY reset, the PHY2_RST and Reset bits are automatically cleared.
No other modules of the LAN9312 are affected by this reset.
In addition to the methods above, the Port 2 PHY is automatically reset after returning from a PHY
power-down mode. This reset differs in that the PHY power-down mode reset does not reload or reset
any of the PHY registers. Refer to
information.
Port 2 PHY reset completion can be determined by polling the PHY2_RST bit in the

Port 1 PHY Reset
A Port 1 PHY reset is performed by setting the PHY1_RST bit of the
