Receiver Enable (RXEN)
When set (1), the MAC’s receiver is enabled and will receive frames from
the internal PHY. When reset, the MAC’s receiver is disabled and will not
receive any frames from the internal PHY.

Note:
RESERVED
In order to successfully enable the receive path, the RX DMAC
must be enabled by setting the Start/Stop Receive bit (SR) bit of
the
(DMAC_CONTROL)
RXEN).
In order to successfully disable the receive path, the receiver must
be disabled (by clearing RXEN) prior to disabling the RX DMAC
(by clearing the Start/Stop Receive bit (SR) bit of the
Controller Control (Operation Mode) Register
(DMAC_CONTROL)). Otherwise, RX DMA will not stop
(DMAC_STATUS will continue to show the Receive Process State
(RS) as Running and Receive Process Stopped (RPS) does not
assert).
