must be defined before using this function.

Example

‘ set compact flash pinout

dim Cf_Data_Port as byte at PORTD

dim CF_RDY as sbit at RB7_bit

dim CF_WE as sbit at LATB6_bit ‘ for writing to output pin always use latch

dim CF_CD1 as sbit at RB4_bit

dim CF_CE1 as sbit at LATB3_bit ‘ for writing to output pin always use latch

dim CF_A2 as sbit at LATB2_bit ‘ for writing to output pin always use latch

dim CF_A1 as sbit at LATB1_bit ‘ for writing to output pin always use latch

dim CF_A0 as sbit at LATB0_bit ‘ for writing to output pin always use latch

dim CF_RDY_direction as sbit at TRISB7_bit

dim CF_WE_direction as sbit at TRISB6_bit

dim CF_OE_direction as sbit at TRISB5_bit

dim CF_CD1_direction as sbit at TRISB4_bit
