procedure Spi_Ethernet_putByte(v: byte);

Nothing.

This is MAC module routine. It stores one byte to address pointed by the cur-
rent 

ENC28J60

write pointer (EWRPT). 

Parameters:

- 

v

: value to store 

Ethernet module has to be initialized. See Spi_Ethernet_Init.

var data as byte;
...
Spi_Ethernet_putByte(data); // put an byte into ENC28J60 buffer

procedure Spi_Ethernet_putBytes(ptr : ^byte; n : byte);

Nothing.

This is MAC module routine. It stores requested number of bytes into 

ENC28J60

RAM starting from current 

ENC28J60

write pointer (EWRPT) location.

Parameters:

- 

ptr

: RAM buffer containing bytes to be written into ENC28J60 RAM. 

- 

n

: number of bytes to be written. 

Ethernet module has to be initialized. See Spi_Ethernet_Init.

buffer : 

array[17] of byte;

...

buffer := 'mikroElektronika';

...

Spi_Ethernet_putBytes(buffer, 16); // put an RAM array into

ENC28J60 buffer
