sub procedure Spi_Ethernet_getBytes(dim ptr as ^byte, dim addr as
word, dim n as byte)

Nothing.

This is MAC module routine. It fetches equested number of bytes from

ENC28J60

RAM starting from given address. If value of 

0xFFFF

is passed as the

address parameter, the reading will start from current 

ENC28J60

read pointer

(

ERDPT

) location.

Parameters:

- 

ptr:

buffer for storing bytes read from 

ENC28J60

RAM. 

- 

addr: ENC28J60

RAM start address. Valid values: 

0..8192

. 

- 

n:

number of bytes to be read. 

Ethernet module has to be initialized. See Spi_Ethernet_Init.

...
Spi_Ethernet_getBytes(buffer, 0x100, 16) ' read 16 bytes,

starting from address 0x100
