Initialization active. When this bit is written ‘1’, 80 SD clocks are sent to the card. After the 80 clocks are sent,
this bit is self-cleared. This bit is very useful during the card power-up period when 74 SD clocks are needed and
clock auto-gating feature is enabled.
Writing one to this bit when it is already set has no effect. Clearing this bit at any time does not affect it. When
PRSSTAT[CIHB] or PRSSTAT[CDIHB] is set, writing a one to this bit is ignored. That is, when the command line
or data line is active, writing to this bit is not allowed.
Software reset for SDHC_DAT line. The DMA and part of the data circuit are reset. The following registers and
bits are cleared by this bit:
0 Work
1 Reset
Software reset for SDHC_CMD line. Only part of the command circuit is reset. The following registers and bits
are cleared by this bit:
0 Work
1 Reset
Software reset for all. This reset affects the entire host controller except for the card-detection circuit. Register
bits of type ROC, RW, RW1C, and RWAC are cleared.
During its initialization, the host driver should set this bit to reset the eSDHC. The eSDHC should clear this bit
when capabilities registers are valid and the host driver can read them. Additional use of the this bit does not
affect the value of the capabilities registers. After this bit is set, it is recommended the host driver reset the
external card and re-initialize it.
