7.5.2 EMC Register Mapping
This set of registers is used to convey status/control information to/from the Ethernet MAC controller.
These registers are used for loading commands generated by user, indicating transmit and receive
status, buffering data to/from memory, and providing interrupt control. The registers used by
W90N740 EMC (Ethernet MAC controller) are divided into three groups:
Note: registers are named as xxxx_0 or xxxx_1, where xxxx_0 is the register in EMC 0, and xxxx_1 is
the register in EMC 1.
