The slope reference voltage divider circuit, consisting
of a buffer amplifier and resistor divider, is connected to
the internal bandgap reference producing two other
voltage references called SREFHI and SREFLO (see
Figure 9-2). SREFHI is nominally the same as the
bandgap voltage, 1.2V, and SREFLO is nominally
0.13V. These reference voltages are available on two
of the analog multiplexer channels. The A/D module
and firmware can measure the SREFHI and SREFLO
voltages, and in conjunction with the K
ibration data correct for the A/D's offset and slope
errors. See AN624 for further details.

The internal temperature sensor is connected to the
channel 7 input of the A/D converter. The sensor volt-
age is 1.05V nominal at 25 C and its temperature coef-
ficient is approximately 3.7mV/ C. The sensor voltage
at 25 C and the temperature coefficient values are
stored in the calibration space EPROM (See
Table 4-2). To enable the temperature sensor, the
TEMPOFF bit (SLPCON<1>) must be cleared.
