R/W

Transmit Flow Control Operating mode

0: Transmit flow control function is disabled

1: Transmit flow control function is enabled

15 to 13



All 0

Reserved

These bits are always read as 0. The write value

should always be 0.

PRCEF

R/W

Permit Receive CRC Error Frame

0: A frame with a CRC error is received as a frame

with an error.

1: A frame with a CRC error is received as a frame

without an error.

For a frame with an error, a CRC error is reflected in

ECSR of the E-DMAC and the status of the receive

descriptor. For a frame without an error, the frame is

received as normal frame.



All 0

Reserved

These bits are always read as 0. The write value

should always be 0.

MPDE

R/W

Magic Packet Detection Enable

Enables or disables Magic Packet detection by

hardware to allow activation from the Ethernet.

0: Magic Packet detection is not enabled

1: Magic Packet detection is enabled

8, 7



All 0

Reserved

These bits are always read as 0. The write value

should always be 0.

R/W

Reception Enable

If a frame is being received when this bit is switched

from receive function enabled (RE = 1) to disabled

(RE = 0), the receive function will be enabled until

reception of the corresponding frame is completed.

0: Receive function is disabled

1: Receive function is enabled
