Figure 9. Compact Flash Card Writer Application Example

Table 3. Compact Flash Card Writer Pin Assignment

(1) This line shows if the ST72F65 pin is controlled by the

ST7 core or by the DTC.

(2) These lines are not controlled by the DTC but by the

user software running on the ST7 core. The choice of

ST72F65 pin is at the customer’s discretion. The pins

shown here are given only as an example.

(3) As this is a single power supply application, the US-

BEN function in not needed. Thus PF4/USBEN pin can be

used as a normal I/O by configuring it as such by the op-

tion byte.
