are read the 4 LSb’s are latched into their respective bits in the A/D Converter LSbs Register. This

-127.9375 ºC < Temp < 127.9375 ºC and Voltage Range: 0 < Voltage < 256.9375) . See the DC
Characteristics for the accuracy of the reading values.
The eight most significant bits of the 12-bit averaged readings are stored in Reading registers and
compared with Limit registers. The Interrupt Status Register bits are asserted if the corresponding
measured value(s) on the inputs violate their programmed limits.
