procedure Cf_Read_Sector(sector_number : dword; var buffer :
array[512] of byte);

Nothing.

Reads one sector (512 bytes). Read data is stored into buffer provided by the
buffer parameter.

Parameters : 

- 

sector_number

: sector to be read. 

- 

buffer

: data buffer of at least 512 bytes in length. 

The corresponding MCU ports must be appropriately initialized for CF card. See
Cf_Init.

// read sector 22
var data : array[512] of byte;
...
Cf_Read_Sector(22, data);

procedure Cf_Write_Sector(sector_number : dword; var buffer :
array[512] of byte) ;

Nothing.

Writes 512 bytes of data provided by the buffer parameter to one CF sector.

Parameters : 

- 

sector_number

: sector to be written to. 

- 

buffer

: data buffer of 512 bytes in length. 

The corresponding MCU ports must be appropriately initialized for CF card. See
Cf_Init.

// write to sector 22
var data : array[512] of byte;
...

Cf_Write_Sector(22, data);
