19.7
Table 19.6 lists the MCIF interrupt sources. The interrupt sources are classified into three groups,
each to which an interrupt vector is assigned. Each interrupt source can be individually enabled by
the enable bits in INTCR0 and INTCR1. A disabled interrupt source does not set the flag.
The MMCIA interrupts can be used as DTC activation interrupt sources.
