Detailed Description

HW_SDHC_PROCTL - Protocol Control register (RW)

Reset value: 0x00000020U

There are three cases to restart the transfer after stop at the block gap. Which case is appropriate depends on whether the SDHC issues a suspend command or the SD card accepts the suspend command: If the host driver does not issue a suspend command, the continue request shall be used to restart the transfer. If the host driver issues a suspend command and the SD card accepts it, a resume command shall be used to restart the transfer. If the host driver issues a suspend command and the SD card does not accept it, the continue request shall be used to restart the transfer. Any time stop at block gap request stops the data transfer, the host driver shall wait for a transfer complete (in the interrupt status register), before attempting to restart the transfer. When restarting the data transfer by continue request, the host driver shall clear the stop at block gap request before or simultaneously.
