The real-time watch cannot be set more than 2 points. However, an interval watch is provided on the DTU8 as a function that allows you to set more than 2 watch items. The interval watch repeats the operation of emulating for the set interval time, breaking, reading the value of the item registered in the watch window, displaying it, and then restarting the emulation. It also provides a function that allows you to set whether to continue or stop the operation of peripheral circuits during a break. By using this function together, for example, if the functional timer is set to operate even during a break, you can check the register update with the interval watch without stopping the PWM output.
