configure profile table, and then execute PLS instruction.
Each PTO/PWM generator also provides a status bytes in SM area, user can get the status information of
PTO/PWM generator from the status bytes, as shown in following table.

The fallowing takes PTO0 as an example to introduce how to configure and operate the PTO/PWM generator
in the user program.
There are two procedures for using PTO: Configure related control registers and initialize PTO. Execute PLS
instruction.
Use SM0.1 (the first scan memory bit) to call a subroutine that contains the initialization instructions. Since
SM0.1 is used, the subroutine shall be executed only once, and this reduces CPU scan time and provides a
better program structure.
