+Description:
+ Count mode for channel Y. The ceiling and floor values for

+ count modes are available:
+
+ normal:
+ Counting is continuous in either direction.
+
+ range limit:
+ An upper or lower limit is set, mimicking limit switches
+ in the mechanical counterpart. The upper limit is set to

+ to the Count Y floor value. The counter freezes at
+ count = ceiling when counting up, and at count = floor
+ when counting down. At either of these limits, the
+ counting is resumed only when the count direction is
+ reversed.
+
+ non-recycle:
+ The counter is disabled whenever a counter overflow or
+ underflow takes place. The counter is re-enabled when a
+ new count value is loaded to the counter via a preset
+ operation or direct write.
+
+ modulo-n:
+ A count value boundary is set between the Count Y floor
+ value and the Count Y ceiling value. The counter is
+ reset to the Count Y floor value at count = ceiling when
+ counting up, while the counter is set to the Count Y
+ ceiling value at count = floor when counting down; the

+Description:
+ Read-only attribute that indicates the count direction of Count
+ Y. Two count directions are available: forward and backward.
+
+ Some counter devices are able to determine the direction of
+ their counting. For example, quadrature encoding counters can
+ determine the direction of movement by evaluating the leading

+ This attribute exposes such count directions.

+KernelVersion: 5.2
+Contact: linux-iio@vger.kernel.org
+Description:
+ Whether channel Y counter is enabled. Valid attribute values are
+ boolean.
+
+ This attribute is intended to serve as a pause/unpause mechanism
+ for Count Y. Suppose a counter device is used to count the total
+ movement of a conveyor belt: this attribute allows an operator
+ to temporarily pause the counter, service the conveyor belt,
+ and then finally unpause the counter to continue where it had
+ left off.

+
+ increase:
+ Accumulated count is incremented.
+
+ decrease:
+ Accumulated count is decremented.
+
+ pulse-direction:
+ Rising edges on signal A updates the respective count.
+ The input level of signal B determines direction.
+
+ quadrature x1 a:
+ If direction is forward, rising edges on quadrature pair
+ signal A updates the respective count; if the direction
+ is backward, falling edges on quadrature pair signal A
+ updates the respective count. Quadrature encoding
+ determines the direction.

+ Any state transition on quadrature pair signal A updates
+ the respective count. Quadrature encoding determines the
+ direction.
+
