Step 2. Counter Control Signal
●
Counter functions can set mask or clear with counter control signal.
●
There are two types of counter control signals as follows:
Control
by external input terminal
and
Control by programming
. Both
allow counter control.
Control by external input terminal
Control Signals (External input terminal)
Control by programming
Control Signals (Internal output terminal)
• Make sure to access shared memory by 2 word units.
• Internal connection between the counter and pulse/PWM
output is fixed on the CHs for counter and pulse/PWM
output.
• When pulse/PWM output are internally connected to
counter, the input mode of counter is automatically
configured to the input mode. Be careful that previously
configured counter input mode is ignored.
