function Spi_Ethernet_putConstString(const ptr : ^byte): word;

Number of bytes written into 

ENC28J60

RAM.

This is MAC module routine. It stores whole const string (excluding null termination)
into 

ENC28J60

RAM starting from current 

ENC28J60

write pointer (EWRPT) location.

Parameters:

- 

ptr

: const string to be written into 

ENC28J60

RAM. 

Ethernet module has to be initialized. See Spi_Ethernet_Init.

buffer : 

string[16];

...
buffer := 'mikroElektronika';

...

Spi_Ethernet_putConstString(buffer); // put a const string into

ENC28J60 buffer

function Spi_Ethernet_getByte(): byte;

Byte read from 

ENC28J60

RAM.

This is MAC module routine. It fetches a byte from address pointed to by cur-
rent 

ENC28J60

read pointer (

ERDPT

).

Ethernet module has to be initialized. See Spi_Ethernet_Init.

var buffer : byte; 
...

buffer := Spi_Ethernet_getByte(); // read a byte from ENC28J60
