MII_MODE
Description
If set, frames with DA (destination address) equal to 0xFFFF_FFFF_FFFF are rejected unless the PROM
bit is set. If BC_REJ and PROM are set, frames with broadcast DA are accepted and the M (MISS) is set
in the receive buffer descriptor.
Promiscuous mode. All frames are accepted regardless of address matching.

1 Enabled
Media independent interface mode
This bit must always be set.

0 Reserved.
1 MII or RMII mode, as indicated by the RMII_MODE bit
Disable receive on transmit
0 Receive path operates independently of transmit (use for full duplex or to monitor transmit activity in
half duplex mode).
1 Disable reception of frames while transmitting (normally used for half duplex mode).
Internal loopback
0 Loopback disabled.
1 Transmitted frames are looped back internal to the device and transmit MII output signals are not
asserted. DRT must be cleared. .
44.3.10 Transmit Control Register (ENET_TCR)
TCR is read/write and configures the transmit block. This register is cleared at system
reset. FDEN can only be modified when ECR[ETHER_EN] is cleared.
Address: ENET_TCR is 400C_0000h base + C4h offset = 400C_00C4h
