Register Description – General Purpose I/O Memory
ADCACAL1 - ADCA Calibration Register 1
TEMPSENSE0 - Temperature Sensor Calibration Register 0
TEMPSENSE1 - Temperature Sensor Calibration Register 1
GPIORn – General Purpose I/O Register n
• 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.
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.
• Bit 7:0 - TEMPSENSE0[7:0] - Temperature Sensor Calibration Byte 0
This byte contains the byte 0 (8 LSB) of the temperature measurement.
• Bit 7:0 - TEMPSENSE1[7:0] - Temperature Sensor Calibration Byte 1
This byte contains byte 1 of the temperature measurement.
This is a general purpose register that can be used to store data such as global variables in the
bit accessible I/O memory space.
