Counting range Same as the counter timer block
Type Addition, subtraction, linear counter mode, ring counter mode, addition mode, preset
counter function, latch counter function
Minimum count pulse width (duty 1-phase input (1 multiple/2 multiples),
ratio: 50%) CW/CCW
2-phase input (1 multiple/2 multiples/4
multiples)
Comparison range 32-bit signed binary value, 32-bit unsigned binary value, 16-bit signed binary value,
16-bit unsigned binary value
Comparison method Setting value < count value, setting value = count value, setting value > count value
Interrupt Coincidence detection interrupt function
Number of steps Up to 16 steps/1 block
The ON/OFF timing can be adjusted in increments of 25ns at a minimum using
trigger input as the starting point.
Output frequency range Max. 2MHz
Duty ratio Any value (Can be set in increments of 25ns at a minimum.)
Number of output pulses = (1 to 2147483647)/(1 to 2147483647) × Number of input
Ratio setting range
pulses
Note that a value obtained by dividing (1 to 2147483647) by (1 to 2147483647)
should not exceed 1.
Measurement item Pulse width (ON width, OFF width, from a rising edge to the next rising edge, from a
falling edge to the next falling edge)
