Prototype
sub procedure Cf_Init()
Description Initializes ports appropriately for communication with CF card.
Parameters None.
Returns Nothing.
Requires Global variables:
- CF_Data_Port : Compact Flash data port
- CF_RDY : Ready signal line
- CF_WE : Write enable signal line
- CF_OE : Output enable signal line
- CF_CD1 : Chip detect signal line
- CF_CE1 : Enable signal line
- CF_A2 : Address pin 2
- CF_A1 : Address pin 1
- CF_A0 : Address pin 0
- CF_RDY_direction : Direction of the Ready pin
- CF_WE_direction : Direction of the Write enable pin
- CF_OE_direction : Direction of the Output enable pin
- CF_CD1_direction : Direction of the Chip detect pin
- CF_CE1_direction : Direction of the Chip enable pin
- CF_A2_direction : Direction of the Address 2 pin
- CF_A1_direction : Direction of the Address 1 pin
- CF_A0_direction : Direction of the Address 0 pin
must be dened before using this function.
