12-bit mode, left adjusted
• 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.
• Bits 7:0 - RES[7:0]: ADC Channel Result, low byte
These are the 8 LSB of the ADC result.
• Bits 7:4 - RES[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 with future devices,
always write these bits to zero when this register is written.
