Table 1 : Host Interface signals group
Interrupt to host system
When the polarity is active high, this signal must be pulled low, otherwise pulled
high in active low environment. Software set the bit6 of command register (CMD) to
response the polarity.
Reset signal: active low.
Reference Clock. This clock may be from host (synchronous mode) or the output of
stand-alone OSC (asynchronous mode).
Wake-up signal to system. When the polarity of system is active high, this signal
must be pulled low, otherwise pulled high in active low environment. Software set
the bit0 of command register (CMD) to response the polarity.
