Eth_Inport(unsigned short address);

One byte from the specified address.

Retrieves a byte from the specified address of the Ethernet card chip.

The card (NIC) must be properly initialized. See 

Eth_Init

.

udp_length |= Eth_Inport(NIC_DATA);

Eth_Scan_For_Event(unsigned short *next_ptr);

Type of the ethernet packet received. Two types are distinguished: 

ARP

(MAC-IP

address data request) and 

IP

(Internet Protocol).

Retrieves sender’s MAC (hardware) address and type of the packet received. The 
function argument is an (internal) pointer to the next data packet in RTL8019’s buffer,
and is of no particular importance to the end user.

The card (NIC) must be properly initialized. See 

Eth_Init

. Also, the function must be

called in a proper sequence, i.e. right after the card init, and IP address/UDP port init.

Eth_Init(&PORTB, &PORTD, &PORTE, 2, 1, 0);

Eth_Set_Ip_Address(192u, 168u, 20u, 25u);

Eth_Set_Udp_Port(10001);

{ 

// Main block of every Ethernet example

event_type = Eth_Scan_For_Event(&next_ptr);

(event_type) {

(event_type) {case ARP: Arp_Event(); break;

IP : Ip_Event();}

Eth_Outport(CR, 0x22);

Eth_Outport(BNDRY, next_ptr);

}
