+Siemens SLE44xx Chip Card Protocol
+------------------------------------------------------------------------
+
+SLE 4418/4428/4432/4442 memory cards implement a 2-wire protocol for data
+communication (signals CLK and I/O). A RST signal can be used to terminate
+currently pending long memory reads, and resets the card's address counter
+when combined with CLK. The next response data then is the Answer to Reset
+(ATR) which identifies the chip's capabilities, and allows to adjust for
+subsequent communication of more requests.
