Well i managed to read the ATR 4 bytes response from the SLE4442 smart card.

The problem i am facing now is how to send the command "Read main memory" to smart card.

I have understood the command "read main memory" but i cannot understand the following:

"Command Mode
After the Answer-to-Reset the chip waits for a command. Every command begins with a start
condition, includes a 3 bytes long command entry followed by an additional clock pulse and ends
with a stop condition.
– Start condition: Falling edge on I/O during CLK in level H
– Stop condition: Rising edge on I/O during CLK in level H
After the reception of a command there are two possible modes:
– Outgoing data mode for reading
– Processing mode for writing and erasing
Answer-to-Reset
(Hex)
Byte 1 Byte 2 Byte 3 Byte 4
DO7…DO0 DO15… DO8 DO23…DO16 DO31…DO24"

What do they mean by "start & stop conditions" Do i have to do it manualy from my microcontroller? Do i have to CLR or SETB the I/O line during CLK in high level?

Any comments are is acceptable.
