The ADMA engine does not support the suspend/resume function. However, the stop and continue functions are available.
When the stop-at-block-gap request (the MMCHS_HCTL[16] SBGR bit) is set during the ADMA operation, the block gap event interrupt is generated when the ADMA is stopped at block gap (the MMCHS_STAT[2] BGE bit). The host controller must stop the ADMA read operation by using read wait or by stopping the SD clock. While stopping ADMA, SD commands cannot be issued.
