Analogue Comparator 1,
Level High [6112]
Sets the analogue comparator high level, with range
according to the selected value in menu [6111].
Example
This example describes, both for hysteresis and window type
comparators, the normal use of the constant level high and
low. The function is used for temperature control. Follow the
step by step explanation in Table 31 and Table 32.

No. Description
Hysteresis
1
The reference signal passes the Level LO
value from below (positive edge), the
comparator CA1 does not change, output
stays low.
2
The reference signal passes the Level HI
value from below (positive edge), the
comparator CA1 output is set high.
3
The reference signal passes the Level HI
value from above (negative edge), the
comparator CA1 does not change, output
stays high.
4
The reference signal passes the Level LO
value from above (negative edge), the
comparator CA1 is reset, output is set low.
5
The reference signal passes the Level LO
value from below (positive edge), the
comparator CA1 does not change, output
stays low.
6
The reference signal passes the Level HI
value from below (positive edge), the
comparator CA1 output is set high.
7
The reference signal passes the Level HI
value from above (negative edge), the
comparator CA1 does not change, output
stays high.
8
The reference signal passes the Level LO
value from above (negative edge), the
comparator CA1 is reset, output is set low.
