Period latest value
The latest value of the period is stored.
• When logic switching is set to positive logic, the difference from the previous rising edge up to the latest
rising edge.
• When logic switching is set to negative logic, the difference from the previous falling edge up to the latest
falling edge.

Same as the rising edge ring counter value (Page 271 Rising edge ring counter value)
Period maximum value
The maximum value of the period is stored.
• 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 falling edge to falling edge.
• The maximum value of the period can be changed only by the HCMOV/DHCMOV instruction.
