The temperature sensor connects to the highest order input of the ADC2 input multiplexer (see
“7. 10-Bit ADC (ADC2, C8051F060/1/2/3)” on page
ables the temperature sensor. While disabled, the temperature sensor defaults to a high impedance state,
and any A/D measurements performed on the sensor while disabled result in meaningless data.
