- Field
DIRPOL
reader - Data and command direction signals polarity selection. This bit can only be written when the SDMMC is in the power-off state (PWRCTRL = 00). - Field
DIRPOL
writer - Data and command direction signals polarity selection. This bit can only be written when the SDMMC is in the power-off state (PWRCTRL = 00). - Field
PWRCTRL
reader - SDMMC state control bits. These bits can only be written when the SDMMC is not in the power-on state (PWRCTRL?11). These bits are used to define the functional state of the SDMMC signals: Any further write will be ignored, PWRCTRL value will keep 11. - Field

VSWITCHEN
reader - Voltage switch procedure enable. This bit can only be written by firmware when CPSM is disabled (CPSMEN = 0). This bit is used to stop the SDMMC_CK after the voltage switch command response: - Field

VSWITCH
reader - Voltage switch sequence start. This bit is used to start the timing critical section of the voltage switch sequence: - Field
