31.6 MMCIF Interrupt Sources
Table 31.8 lists the MMCIF interrupt sources. The interrupt sources are classified into four groups,
and four interrupt vectors are assigned. Each interrupt source can be individually enabled by the
enable bits in INTCR0 to INTCR2. Disabled interrupt sources do not set a flag.
