Interrupt of I C interface, DMA transfer, and EI
Table 27.4-1 shows the relationship between the interrupt source, interrupt vector, and interrupt
control register other than software interrupt.

For details, see Table 3.2-2.
Note:
If there are two interrupt sources in the same interrupt number, resource clears both
interrupt request flags. Therefore, when one of two sources uses the EI
function, the other interrupt function cannot use. The interrupt request enable bit of the
relevant resource is set to 0 to execute the software polling processing.
