Section 23 Gigabit Ethernet Controller (GETHER)
23.3.2
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.

These bits are always read as 0. The write value should
always be 0.
Counter Clear Mode
Sets the method for clearing the counter register. Refer
to the description of each register.
0: Cleared to 0 by writing H'11111111 to the relevant
1: Cleared to 0 when the relevant register is read
Reserved
These bits are always read as 0. The write value should
always be 0.
