详细说明： The SDIO (SD Input/Output) card is based on and compatible with the SD memory card. This compatibility includes mechanical, electrical, power, signaling and software. The intent of the SDIO card is to provide high-speed data I/O with low power consumption for mo bile electronic devices. A primary goal is that an SDIO card inserted into a non-SDIO aware host shall cause no physical damage or disruption of that host or it’s software. In this case, the SDIO card should simply be ignored. Once inserted into an SDIO aware host, the detection of the card proceeds via the normal means described in this specification with some extensions. In this state, the SDIO card is idle and draws a small amount of power (15 mA averaged over 1 second). During the normal initialization and interrogation of the card by the host, the card identifies itself as an SDIO card. The host software then obtains the card information in a tuple (linked list) format and determines if that card’s I/O function(s) are acceptable to activate. This decision is based on such parameters as power requirements or the availability of appropriate software drivers. If the card is acceptable, it is allowed to power up fully and start the I/O function(s) built into it. ...展开收缩
