Programmable Registers
29.9.2 ENET SWI Scratch Register (HW_ENET_SWI_SCRATCH)
The Scratch Register provides a memory location to test the register access. It returns all
data written to it in inverted form.

29.9.3 ENET SWI Port Enable Bits. (HW_ENET_SWI_PORT_ENA)
Port Enable Bits. Two bits per port. The transmit and receive direction for each port can be
independently enabled. When the transmit direction is enabled a frame can be forwarded
to the port. When disabled, all frames forwarded to the port are discarded. When the receive
direction is enabled the port is selected and a frame is accepted if it indicates data available.
If the receive direction is disabled the input is ignored and never selected for frame reception.
