Function Explanation

The GPWM instruction is used in the pulse output.

Please use GPWM instruction in the freewheeling task. Otherwise the output of GPWM instruction
may be inaccurate.

The values of In1 and In2 can be modified while GPWM instruction is being executed.

When In1
≤ 0,
the pulse output register has no output. When In1
≥
in2, the pulse output register is
always ON.

The output of GPWM instruction can use a variable or any bit register. For details, refer to “Section
3.1.2 Registers and Data Types”.
