Description
Management data read from MDIO pin.
Defines the operation mode of the PHY.
The management data writes to the PHY through MDIO pin.
MII management clock is used as timing reference of MDIO signal
When set together with SSR(CSR9<11>), the MX98713 performs a read cycle from the
serial ROM. When set and SSR is reset, the MX98713 performs a write cycle to PHY.
When set together with SSR, the MX98713 executes a write cycle to the serial ROM. When
set and SSR is reset, the MX98713 executes a write cycle to the PHY.
When set together with either SRO(CSR9<14>) or SWO(CSR9 <13>), the MX98713 selects
the serial ROM.
Serial ROM data out from serial ROM into the MX98713.
Serial ROM data input to serial ROM from the MX98713.
Serial clock output to serial ROM.
