The interrupt request is generated each time an unmasked flag is set, and the global MMC con-
troller interrupt enable bit is set (EMMC in IEN1 register).
Reading the MMINT register automatically clears the interrupt flags (acknowledgment). This
implies that register content must be saved and tested interrupt flag by interrupt flag to be sure
not to overlook any interrupts.
