SDR25 speed mode requires 1.8-V signaling. Note that even if a card supports UHS-I modes (for example
SDR50, SDR104, DDR50) it can still communicate at the lower speeds (for example SDR12, SDR25).

Where supported, controls the voltage switch output to support 1.8-V signalling for SD.

SPI mode is obsolete in the MMC 4.41 specification.
(31)
Supports a maximum clock rate of 50 MHz instead of 52 MHz (specified in MMC specification).
