11 Count value ceiling for Count Y. This is the upper limit for the
18 Count value floor for Count Y. This is the lower limit for the
25 Count mode for channel Y. The ceiling and floor values for
26 Count Y are used by the count mode where required. The following
27 count modes are available:
35 the Count Y ceiling value, while the lower limit is set
