The pulse widths of the signal at the input IN2 / IN5 (PULSE) are measured with a
programmable time base (f
ref
, see figure Counter access").
The measuring process starts with a HIGH−LOW edge at input IN2 / IN5 (PULSE)
and ends with the LOW−HIGH edge.
A LOW−HIGH edge of the measured signal stores the pulse width with the unit
1/f
ref
. This result can be found and read out in the data output range until the next
result appears.
The counting direction is determined via the signal level at input IN3 / IN6 (DIR).
Upcounter: LOW level
Downcounter: HIGH level
During the counting process, a LOW level must be applied to input IN1 / IN4 (RES).
A HIGH level deletes the counter.
Output OUT0 / OUT1 has no function.
