TEMPERATURE

[11:0] TEMPERATURE: Temperature reading

Absolute temperature

= ( VIO * temperature [11:0] ) / 7.51 (12-bit ADC)

= ( VIO * temperature [9:0] ) / 7.51 (10-bit ADC)

Note that VIO is used as a reference in temperature acquisition.

Variations in VIO will directly affect the accuracy of temperature acquired.
