Comparator inputs can be externally driven from -0.25 V to (VDD) + 0.25 V without damage or upset. The
complete electrical specifications for the Comparator are given in Table 12.1.
The Comparator response time may be configured in software using the CPnMD1-0 bits in register CPT-
nMD (see Figure 12.4). Selecting a longer response time reduces the amount of power consumed by the
comparator. See Table 12.1 for complete timing and current consumption specifications.
The hysteresis of the Comparator is software-programmable via its Comparator Control register (CPT-
nCN). The user can program both the amount of hysteresis voltage (referred to the input voltage) and the
positive and negative-going symmetry of this hysteresis around the threshold voltage.
The Comparator hysteresis is programmed using Bits3-0 in the Comparator Control Register CPTnCN
(shown in Figure 12.3). The amount of negative hysteresis voltage is determined by the settings of the
CPnHYN bits. As shown in Figure 12.2, the negative hysteresis can be programmed to three different set-
tings, or negative hysteresis can be disabled. In a similar way, the amount of positive hysteresis is deter-
mined by the setting the CPnHYP bits.
