There are three ways to restart the transfer after a stop at the block gap. The appropriate method depends
on whether the eSDHC issues a suspend command or the SD card accepts the suspend command:
Any time PROCTL[SABGREQ] stops the data transfer, the host driver should wait for IRQSTAT[TC]
before attempting to restart the transfer. When restarting the data transfer by continue request, the host
driver should clear PROCTL[SABGREQ] before or simultaneously.

If the host driver does not issue a suspend command, the continue request should be used to restart
the transfer.
If the host driver issues a suspend command and the SD card accepts it, a resume command should
be used to restart the transfer.
If the host driver issues a suspend command and the SD card does not accept it, PROCTL[CREQ]
should be used to restart the transfer.

System Control Register (SYSCTL)
SDHC_DAT3 as card detection pin. If this bit is set, SDHC_DAT3 should be pulled down to act as a card detection
pin. Be cautious when using this feature, because SDHC_DAT3 is chip-select for SPI mode, and a pull-down on
this pin and CMD0 may set the card into SPI mode, which the eSDHC does not support.
0 SDHC_DAT3 does not monitor card insertion
1 SDHC_DAT3 is card detection pin
Data transfer width. Selects the data width of the SD bus. The host driver should set it to match the data width
of the card.
