Description
DcotCounterEnhDebounceTime
Sets debounce to:
DcovCounterEnhDebounce500ns = 0
500 ns
DcovCounterEnhDebounce1500ns = 1
1500 ns
DcovCounterEnhDebounce3500ns = 2

15500 ns
DcovCounterEnhDebounce31500ns = 5
31500 ns
DcovCounterEnhDebounce63500ns = 6
63500 ns
DcovCounterEnhDebounce127500ns = 7
127500 ns
DcovCounterEnhDebounce100us = 8
100 µs
DcovCounterEnhDebounce300us = 9
300 µs
DcovCounterEnhDebounce700us = 10
700 µs
DcovCounterEnhDebounce1500us = 11
1500 µs
DcovCounterEnhDebounce3100us = 12
3100 µs
DcovCounterEnhDebounce6300us = 13
6300 µs
DcovCounterEnhDebounce12700us = 14
12700 µs
DcovCounterEnhDebounce25500us = 15
25500 µs
Used to bypass the debounce mode, or to set a
channel’s comparator output to one of 16
debounce times. Debounce is used to eliminate
switch-induced transients typically associated
with electro-mechanical devices including relays,
proximity switches, and encoders.
Note that there are two debounce modes, one for
“After Stable” and another for “Before Stable.”
See: DcotCounterEnhDebounceTrigger
DcovCounterEnhDebounceNone = 16
bypass
DcotCounterEnhEdge
Selects for detection:
DcovCounterEnhRisingEdge = 0
The “Rising Edge”
Determines whether the rising edge or falling
edge is to be detected.
DcovCounterEnhFallingEdge = 1
The “Falling Edge”
DcotCounterEnhTickSize
Sets ticksize to:
DcovCounterEnhTick20_83ns
= 0
20.83 ns
DcovCounterEnhTick208_3ns
= 1
208.3 ns
DcovCounterEnhTick2083_3ns
= 2
2 083.3 ns
Determines the ticksize; which is the fundamental
unit of time for period, pulsewidth, and timing
measurements.
DcovCounterEnhTick20833_3ns
= 3
20833.3 ns
DcotCounterEnhControl
DcovCounterEnhDisable = 0
Disables counter
DcovCounterEnhEnable
= 1
Enables counter
DcovCounterEnhClear
= 2
Clears counter
DmotCounterEnhControl
DcovCounterEnhDisable = 0
Disables all counters
DcovCounterEnhEnable = 1
Enables all counters
DcovCounterEnhClear = 2
Clears all counters
Usage Note: Combine the applicable mode with the desired mode-specific settings via option values.
The following three option values are available for all Option Types listed above.
DcovCounterEnhMode_Counter
DcovCounterEnh_ClearOnRead
DcovCounterEnhModeMask_32Bit
