CALH - ADC Calibration value registers
12-bit mode, left adjusted
12-bit mode, right adjusted
8-bit mode
• Bits 7:4 - 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.
• Bits 3:0 - CAL[11:8]: ADC Calibration value
This is the 4 MSB of the 12-bit CAL value.
The CH0RESL and CH0RESH register pair represents the 16-bit value CH0RES. For details on
reading 16-bit register refer to
• Bits 7:0 - CHRES[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 - CHRES[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.
