sub procedure Cf_Read_Init(dim address as longword, dim
sector_count 

as byte)

Nothing.

Initializes CF card for reading.

Parameters : 

- 

address

: the first sector to be prepared for reading operation. 

- 

sector_count

: number of sectors to be prepared for reading operation. 

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

' initialize compact flash for reading from sector 590

Cf_Read_Init(590, 1)

sub function CF_Read_Byte() as byte

Returns a byte read from Compact Flash sector buffer.

Note: Higher byte of the unsigned return value is cleared. 

Reads one byte from Compact Flash sector buffer location currently pointed to
by internal read pointers. These pointers will be autoicremented upon reading.

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

CF card must be initialized for reading operation. See Cf_Read_Init.
