• Bit 0 – IF: ADC Channel Interrupt Flag
The interrupt flag is set when the ADC conversion is complete. If the channel is configured for
compare mode, the flag will be set if the compare condition is met. IF is automatically cleared
when the ADC channel interrupt vector is executed. The bit can also be cleared by writing a one
to the bit location.
For all result registers and with any ADC result resolution, a signed number is represented in 2’s
complement form and the MSB represents the sign bit.
The RESL and RESH register pair represents the 16-bit value ADCRESULT. Reading and writ-
ing 16-bit values require special attention, refer to
details.
• Bits 7:0 - RES[11:4]: ADC Channel Result, high byte
These are the 8 MSB of the 12-bit ADC result.
• Bits 7:4 - Reserved
These bits will in practice be the extension of the sign bit CHRES11 when ADC works in differen-
tial mode and set to zero when ADC works in signed mode.
• Bits 3:0 - RES[11:8]: ADC Channel Result, high byte
These are the 4 MSB of the 12-bit ADC result.
• Bits 7:0 - Reserved
These bits will in practice be the extension of the sign bit CHRES7 when ADC works in signed
mode and set to zero when ADC works in single-ended mode.
