19.7 AUXADC INTERRUPTS
w
The AUXADC has five second-level interrupts which can trigger a first-level System Interrupt,
AUXADC_INT (see Section 24). These are described in Table 119. Each AUXADC interrupt in
Register R26 can be masked by setting the associated mask bit in Register R34.
The AUX_DATARDY_EINT interrupt indicates that new AUXADC data is ready. This bit is cleared
when Register R26 is read. Note that this bit is not cleared by reading the measured AUXADC data
in Registers R152 to R159.
The AUXADC_DCOMPn_EINT interrupts indicate that the selected AUXADC channel on Comparator
‘n’ is beyond the programmed threshold. The DCMPn_GT register bits defined in Table 118 select
whether an interrupt indicates the measured value is above the threshold or indicates the measured
value is below the threshold.
