12-/8-bit mode
12-bit mode, left adjusted
• Bits 7:0 - CHRES[7:0]: ADC Channel Result, low byte
These are the 8 LSB of the ADC result.
• Bits 7:4 - CHRES[3:0]: ADC Channel Result, low byte
These are the 4 LSB of the 12 bit ADC result.
• Bits 3:0 - 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.
The CMPH and CMPL register pair represents the 16-bit value ADC Compare (CMP). For
details on reading and writing 16-bit registers refer to
• Bits 7:0 - CMP[15:0]: ADC Compare value high byte
These are the 8 MSB of the 16-bit ADC compare value. In signed mode, the number representa-
tion is 2's complement and the MSB is the sign bit.
• Bits 7:0 - CMP[7:0]: ADC compare value high byte
These are the 8 LSB of the 16-bit ADC compare value. In signed mode, the number representa-
tion is 2's complement.
