5.2.4.
MAC Raw mode(only supported in socket 0) can be utilized.
{
START:
}
/* sets MAC raw mode */
Sn_MR = 0x04;
/* sets OPEN command */
Sn_CR = OPEN;
/* Check if the value of Socket n Status Register(Sn_SR) is SOCK_MACRAW. */
if (Sn_SR != SOCK_MACRAW) Sn_CR = CLOSE; goto START;
It initializes the socket as MAC raw.
This is same as UDP. Refer to 5.2.2 UDP.
MAC raw received Ethernet packet having packet size information.
In case of MAC raw, 2byte header is attached to the data received. The header structure is as below.
This is same as UDP. Refer to 5.2.2 UDP except that remote_port information is not needed.
