Description
DcotCounterEnhMeasurementMode (continued)
DcovCounterEnhMode_Encoder Encoder Mode
DcovCounterEnhEncoder_X1
DcovCounterEnhEncoder_X2
DcovCounterEnhEncoder_X4
Determines the encoder measurement mode:
1X, 2X, or 4X.
DcovCounterEnhEncoder_LatchOnSOS Selects start of scan. Latches the counter outputs at the
beginning of every scan.
DcovCounterEnhEncoder_LatchOnZ Selects the Encoder Z mapped signal to latch the counter
outputs. This allows the user to know the exact counter
value when an edge is present on another channel.
DcovCounterEnhEncoder_ClearOnZ_Off
DcovCounterEnhEncoder_ClearOnZ_On
Selects “clear on Z” On or Off. When On, the encoder Z
is referenced to clear the counter. The counter is cleared
on the rising edge of the mapped (Z) channel.
DcovCounterEnhModeMask_16Bit Selects 16-Bit counter.
DcovCounterEnhModeMask_32Bit Selects 32-Bit counter.
DcovCounterEnhModeMaskGatingOff
Enumeration
with
Bit-Masking.
The options can
be combined.
DcovCounterEnhModeMaskGatingOn
Gating can be selected On or Off. When “On”, the
counter is enabled when the mapped channel to gate the
counter is high. When the mapped channel is low, the
counter is disabled (but holds the count value).
