6355F–ATARM–12-Mar-13

EMAC_NCFG

0xFFFBC004

Read-write

Set to 1 to indicate 100 Mbit/s operation, 0 for 10 Mbit/s. The value of this pin is reflected on the 

speed

pin.

If set to 1, the transmit block ignores the state of collision and carrier sense and allows receive while transmitting. Also con-
trols the 

half_duplex

pin.

When set to 1, all valid frames are received.

Set to one to enable jumbo frames of up to 10240 bytes to be accepted.

When set to 1, frames addressed to the broadcast address of all ones are not received.

When set, multicast frames are received when the 6-bit hash function of the destination address points to a bit that is set in
the hash register.

When set, unicast frames are received when the 6-bit hash function of the destination address points to a bit that is set in
the hash register.

Setting this bit means the EMAC receives frames up to 1536 bytes in length. Normally, the EMAC would reject any frame
above 1518 bytes.
