Table 2. SmartMedia Interface Pin Assignment
(1): This line shows if the ST72F65 pin is controlled by the
ST7 core or the DTC.
(2): These lines are not controlled by the DTC but by the
user software running on the ST7 core. The ST72F65 pin
choice is at customer discretion. The pins shown here are
only shown as an example.
(3): When a single card is to be handled, PA7 is free for
