SMSC LAN9211

DATASHEET

Soft Reset (SRST). Writing 1 generates a software initiated reset. This reset

generates a full reset of the MAC CSR’s. The SCSR’s (system command

and status registers) are reset except for any NASR bits. Soft reset also

clears any TX or RX errors (TXE/RXE). This bit is self-clearing.

Notes:

Do not attempt a soft reset unless the PHY is fully awake and operational.

After a PHY reset, or when returning from a reduced power state, the PHY

must given adequate time to return to the operational state before a soft

reset can be issued.

The LAN9211 must always be read at least once after power-up, reset, or

upon return from a power-saving state or write operations will not function.
