ADCACAL1 - ADCA Calibration Register 1
ADCBCAL0 - ADCB Calibration Register 0
ADCBCAL1 - ADCB Calibration Register 1
TEMPSENSE0 - Temperature Sensor Calibration Register 0
• 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.
ADCBCAL0 and ADCBCAL1 contains the calibration value for the Analog to Digital Converter
B(ADCB). Calibration of the Analog to Digital Converters are done during production test of the
device. The calibration bytes not loaded automatically into the ADC calibration registers, and
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.
• 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.
TEMPSENSE0 and TEMPSENSE1 contains the 12-bit ADCA value from a temperature mea-
surements done with the internal temperature sensor. The measurements is done in production
test at 85C and can be used for single- or multi-point temperature sensor calibration.
