sub procedure Cf_Read_Sector(dim sector_number as longword, dim
byref buffer as byte[512])

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.

sub procedure Cf_Write_Sector(dim sector_number as longword, dim
byref buffer as byte[512])

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.
