4 IdleTime Pause time, measured by counting internal clock signals in
this 32-bit counter register.
The register contains the number of pulses, from an
internal time reference, counted between the last two
counter value increments (rising edges on signal A). The
register value with the counted pulses is refreshed with a
rising edge on A or when the maximum value is reached.
Accordingly, this register makes it possible to represent
count pulses per time unit for the frequency or speed
measurement. The direction (sign) is determined based on
the evaluation of the signal sequence when in AB quadra-
ture mode.

2 CounterValue Counter value (16-bite incremental encoder counter value)
The counter resolves edges into numbers of pulses and
directions. X1, X2 and X4 encoding are available.

2 LatchValue Stored counter value (stored 16-bit incremental encoder
counter value)
This register contains the counter value stored by a latch
pulse. The input that triggers this action must be config-
ured accordingly.
