PRESCALER - ADC Clock Prescaler register
INTFLAGS - ADC Interrupt Flag register
• Bits 7:3 - Reserved
These bits are reserved and will always read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bits 2:0 - PRESCALER[2:0]: ADC Prescaler configuration
These bits define the ADC clock relative to the Peripheral clock, according to
page
Table 25-7.
• Bits 7:4 - Reserved
These bits are reserved and will always read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bits 3:0 - CH[3:0]IF: Interrupt flags
These flags are set when the ADC conversion is complete for the corresponding ADC channel. If
an ADC channel is configured for compare mode, the corresponding flag will be set if the com-
pare condition is met. CHnIF is automatically cleared when the ADC channel n interrupt vector is
executed. The flag can also be cleared by writing a one to its bit location.
