A/D Converter Interrupt Control
At the end of each conversion, interrupt request flag ADCIR in interrupt control register
ADC_CIC is set. This end-of-conversion interrupt request may cause an interrupt to
vector ADCINT, or it may trigger a PEC data transfer which reads the conversion result
from register ADC_DAT, e.g. to store it into a table in internal RAM for later evaluation.
The interrupt request flag ADEIR in register ADC_EIC will be set either, if a conversion
result overwrites a previous value in register ADC_DAT (error interrupt in standard
mode), or if the result of an injected conversion has been stored into ADC_DAT2 (end-
of-injected-conversion interrupt). This interrupt request may be used to cause an
interrupt to vector ADEINT, or it may trigger a PEC data transfer.
