Differential Window Comparator
Set the DIFFERENTIAL1 bit = 1 in the channel 1 DCL
register to enable the high-speed differential window
comparator. CHV1 and CLV1 control the differential
comparator thresholds. CHV0 and CLV0 are not used
when differential comparison is active. The valid volt-
age range for CHV1 and CLV1 in differential compari-
select one of eight values (0, 2mV, 4mV, 6mV, 8mV,
10mV, 12mV, or 15mV). Hysteresis control affects both
single-ended and differential comparators. The HYST
bits are set to 0b000 at power-up or when RST is forced
low. Table 8 shows the HYST bit functions.

son mode is ±1V. Setting levels outside ±1V does not
damage the device, but performance is not guaran-
teed. Differential comparator outputs are multiplexed to
the channel 0 comparator outputs. The channel 1 com-

parator outputs are both forced to a high state. Figure 4
shows the operation of the comparators. Table 7 shows
the truth table for the differential comparator. Figure 4
shows the comparator block diagram.
Comparator Hysteresis
The DCL calibration register controls the high-speed
comparator hysteresis. The HYST bits of that register
