The module is reinitialized by the hardware (see Table 27-6 for more information about reset signals).
The MMCi.MMCHS_SYSSTATUS[0] RESETDONE bit can be monitored by software to check whether the module is ready to use after a hardware reset.
The functional clock (MMCi_FCLK) and interface clock (MMCi_ICLK) must be provided to the module to allow the RESETDONE status bit to be set.
The debounce clock (MMCi_32K) must be active to reset the module correctly.
This hardware reset signal has a global reset action on the module. All configuration registers and all state-machines are reset in all clock domains.
