• When logic switching is set to positive logic, the difference from rising edge to rising edge.
• When logic switching is set to negative logic, the difference from the previous falling edge up to the latest
falling edge.
• The minimum value of the period can be changed only by the HCMOV/DHCMOV instruction.
■Corresponding devices
