| |
STA control register has areas of mode and opcodes for opeations. 18 bit is using for mode selection, where 0 is old MIO/MDIO access method and 1 is indirect access mode. 19-20 bits are using for setting up read/write operation(STA opcodes). In current state 'read' is set into old MIO/MDIO mode with 19 bit and write operation is set into 18 bit which is mode selection, not a write operation. To correlate write with read we set it into 20 bit.
