24.3.7
The first-level AUXADC_INT interrupt comprises several second-level interrupts for the auxiliary ADC
and associated digital comparators. Each of these has a status bit in Register R26 and a mask bit in
Register R34, as defined in Table 148.

Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Each bit in R34 enables or masks the
corresponding bit in R26. The default
value for these bits is 0 (unmasked).

Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Each bit in R33 enables or masks the
corresponding bit in R25. The default
value for these bits is 0 (unmasked).
