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 LAN9220 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.
