X00 input pulse width should be
greater than the high-speed filter
time (D8021*0.25 us)
In this program, turn on the "Enable Global Interrupts", and set Enable Pulse Capture M8080 to ON at X00.
When the external X00 input switches from OFF to ON, set the pulse capture ag M8090 interrupt to ON.
Process pulse capture events based on the status of M8090, and then reset the pulse capture ag in the
program to facilitate the next pulse capture response.
• To successfully use the pulse capture function, the corresponding input signal pulse width must be greater than
the high-speed lter time. That is, the pulse width must be greater than D8021*0.25 us.
