Revision 2.2 Chapter 4 - SD Card Protocol Description SanDisk SD Card Product Manual Mode 1 Operation-Set Function CMD6 is used in Mode 1 to switch the functionality of the card. Switching to a new functionality is accomplished by performing the following actions. 1. Set the mode bit to 1. 2. Select only one function in each function group. Setting the function to 0x0 selects the default function. It is recommended to specify 0xF (no influence) for all selected functions except for functions that need to be changed. Selecting 0xF will keep the current function that was selected for the function group. In response to a set function, the switch function status will return the following. − The function that is the result of the switch command. In case of invalid selection of one function or more, all set values are ignored and no change will be done (identical to the case where the host selects 0xF for all functions groups). The response to an invalid selection of function will be 0xF. − Maximum current consumption under the selected functions. If one of the selected functions was strong the return value will be 0.
