Atmel AVR XMEGA AU
• 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.
4.17.22
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 test of the device. The calibration bytes are not
loaded automatically into the ADC calibration registers, 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.
4.17.23
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.
4.17.24
TEMPSENSE0 – Temperature Sensor Calibration register 0
TEMPSENSE0 and TEMPSENSE1 contain the 12-bit ADCA value from a temperature measure-
ment done with the internal temperature sensor. The measurement is done in production test 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.
