eMMC Control Register
| CARD_IS_EMMC | eMMC Card Present. This bit indicates the type of card connected. An application program this bit based on the card connected to the SDMMC Host Controller. 0 (Val_0x0): Card connected to the SDMMC Host Controller is a non-eMMC card 1 (Val_0x1): Card connected to the SDMMC Host Controller is an eMMC card |
| DISABLE_DATA_CRC_CHK | Disable Data CRC Check. This bit controls masking of CRC16 error for Card Write in eMMC mode. This is useful in bus testing (CMD19) for an eMMC device. In bus testing, an eMMC card does not send CRC status for a block, which may generate CRC error. This CRC error can be masked using this bit during bus testing. 0 (Val_0x0): DATA CRC check is enabled 1 (Val_0x1): DATA CRC check is disabled |
| EMMC_RST_N | eMMC Device Reset Signal Control. This register field controls SD_RST output of the SDMMC module. 0 (Val_0x0): Reset to eMMC device asserted (active low) 1 (Val_0x1): Reset to eMMC device is de-asserted |
| EMMC_RST_N_OE | Output Enable Control for eMMC Device Reset Signal PAD Control. This field drives SD_RST output of the SDMMC module. 0 (Val_0x0): SD_RST is 0x0 1 (Val_0x1): SD_RST is 0x1 |
