I might be able to help a little, the sle442 does not use the standard i2c interface, hence your problem with accessing it. The rst pin actually controls command read or writes, it does NOT reset the chip.

Next the i2c protocol is not used, it is similar but the bits are reversed, so it cannot be interfaced in the same manner as a 14c02, also it does not use the ninth bit that the i2c spec uses.

Even getting the atr is different to the method used for say the 14c02. Without the datasheet it will be totally impossible to get the all the correct commands for reading or writing to the chip.

One of the biggest problems you will have is the psc code check, this MUST be done by a special procedure before you can even attempt to write to the chip. Failure to to do this within a certain number of attempts will lock out the chip for writing with no way of unlocking it.
