41 XMEGA B [DATASHEET]
8291B–AVR–01/2013
4.16.21 ADCACAL1 – ADCA Calibration register 1

Bit 7:0 – ADCACAL1[7:0]: ADCA Calibration Byte 1
This byte contains byte 1 of the ADCA calibration data, and must be loaded into the ADCA CALH register.
4.16.22 ADCBCAL0 – ADCB Calibration register 0
ADCBCAL0 and ADCBCAL1 contains the calibration value for the analog-to-digital converter B (ADCB). Calibration is
done during production testing of the device. The calibration bytes are not loaded automatically into the ADC calibration
registers, and so this must be done from software.
 Bit 7:0 – ADCBCAL0[7:0]: ADCB Calibration Byte 0
This byte contains byte 0 of the ADCB calibration data, and must be loaded into the ADCB CALL register.
4.16.23 ADCBCAL1 – ADCB Calibration register 1

Bit 7:0 – ADCBCAL0[7:0]: ADCB Calibration Byte 1
This byte contains byte 1 of the ADCB calibration data, and must be loaded into the ADCB CALH register.
4.16.24 TEMPSENSE0 – Temperature Sensor Calibration register 0
TEMPSENSE0 and TEMPSENSE1 contain the 12-bit ADCA value from a temperature measurement done with the
internal temperature sensor. The measurement is done in production testing at 85

C, and can be used for single- or
multi-point temperature sensor calibration.

Bit 7:0 – TEMPSENSE0[7:0]: Temperature Sensor Calibration Byte 0
This byte contains the byte 0 of the temperature measurement.
