7.3.1 EXTERNAL REFERENCE SIGNAL

When external voltage references are used, the

comparator module can be configured to have the com-

parators operate from the same, or different reference

sources. However, threshold detector applications may

require the same reference. The reference signal must

be between VSS and VDD and can be applied to either

pin of the comparator(s).

7.3.2 INTERNAL REFERENCE SIGNAL

The comparator module also allows the selection of an

internally generated voltage reference for the

comparators. Section 8.0, Voltage Reference Module,

contains a detailed description of the Voltage Refer-

ence Module that provides this signal. The internal ref-

erence signal is used when the comparators are in

mode CM<2:0> = 010 (Figure 7-1). In this mode, the

internal voltage reference is applied to the VIN+ pin of

both comparators.

7.4 Comparator Response Time

Response time is the minimum time, after selecting a

new reference voltage or input source, before the

comparator output has a valid level. If the internal ref-

erence is changed, the maximum delay of the internal

voltage reference must be considered when using the

comparator outputs, otherwise the maximum delay of

the comparators should be used (Table 12.1).
