Sir. \ Madam,
What's the equation in calculating current temperature from internal temperature sensor input to ADCA channel 0 result register ?
From the current value in ADCACH0RES = 0x0942 may I calculate the current temperature as of :
current temperature = ( ADCACH0RES current value - 200 ) / ( ( PRODSIGNATURES_TEMPSENSE - 200 ) / 85 ) = ( 0x0942 -200 ) / ( ( 0x0A80 - 200 ) / 85 ) = ( 2370 - 200 ) / ( ( 2688 -200 ) / 85 ) = 74 °C ?
My office AC sets at 22 °C and my DUT is in open air.
ADCA channel 0 result register value = 0x0942:
ADCA temperature sensor calibration value = 0x0A80:
