• Bit 0 - Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bits 7:4 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 3:2 – INTMODE: ADC Interrupt Mode
These bits select the interrupt mode for channel n according to
