Figure 27-49 shows the necessary steps to configure the controller boot mode using CMD0.
To abort a boot sequence, the system must issue a CMD0 with the MMCHS_CMD[23:22] CMD_TYPE bit field set to 0x3 (the MMCHS_CON[17] BOOT_ACK bit previously cleared to 0x0) during the transfer to abort the transfer and enable the card to exit from boot state.
