High−speed counter function
The high−speed counter function counts the input signals, and when the count reaches
the target value, turns on and off the desired output.
The high−speed counter function is able to count high−speed pulses of frequencies up
to 10 kHz.
To turn on an output when the target value is matched, use the target value match on
instruction (F166). To turn off an output, use the target value match off instruction
(F167).
Preset the output to be turned on and off with the SET/RET instruction.
Setting the system register
In order to use the high−speed counter function, it is necessary to set system registers
400 and 401. For detailed information
