Type Aliases

DIRPOL_R

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).

DIRPOL_W

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).

PWRCTRL_R

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.

PWRCTRL_W

Field PWRCTRL writer - 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.

VSWITCHEN_R

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:

VSWITCHEN_W

Field VSWITCHEN writer - 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:

VSWITCH_R

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

VSWITCH_W

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