8266B-MCU Wireless-03/11
application software e.g. to compensate for temperature changes. The internal 1.6V
reference voltage is calibrated and has therefore the highest accuracy compared to the
1.5V or AVDD reference.
• Bit 7 – Res - Reserved Bit
This bit is reserved for future use. A read access always will return zero. A write access
does not modify the content.
• Bit 6:3 – BGCAL_FINE3:0 - Fine Calibration Bits
These bits allow the calibration of the AREF voltage with a resolution of 2mV.
Table 27-14 BGCAL_FINE Register Bits
• Bit 2:0 – BGCAL2:0 - Coarse Calibration Bits
These bits allow the calibration of the AREF voltage with a resolution of 10mV.
