• Bits 7:4 – Reserved
These bits are unused and reserved for future use. For compatibility reasons always write these
bits to zero when this register is written.
• Bit 3:2 – INTMODE[1:]: ADC Interrupt Mode
These bits select the interrupt mode for channel n according to
Table 20-12. ADC Interrupt mode
• Bits 1:0 – INTLVL[1:0]: ADC Interrupt Priority Level and Enable
These bits enable the ADC channel interrupt and select the interrupt level as described in
rupts and Programmable Multi-level Interrupt Controller” on page
be triggered when the IF in the INTFLAGS register is set.
• Bits 7:1 – Reserved
These bits are reserved and will always read as zero. For compatibility reasons always write
these bits to zero when this register is written.
