E-MAC Mode Register (ECMR)
ECMR is a 32-bit readable/writable register that specifies the operating mode of the GETHER.
The settings in this register are normally made in the initialization process following a reset.
The operating mode setting must not be changed while the transmitting and receiving functions
are enabled. To switch the operating mode, return the E-MAC and E-DMAC to their initial states
by means of the SWRT and SWRR bits in EDMR before making settings again.
