 Allow updating the pulse number
2) Set SMD72 according to desired pulse number.
3) Execute the PLS instruction to configure PTO0 and start it, then a new PTO with the
updated pulse number shall be generated.

Execute the PTO (Multiple-Segment Operation)
1) Set control byte SMB67 according to the desired operation.
For example, SMB67 = B#16#A0 indicates:
 Enable the PTO/PWM function
 Select PTO operation
 Select multi-segment operation
 Select 1μs as the time base
2) Set an odd number as the starting position of the profile table into SMW168.
3) Use V area to configure the profile table.
4) (Optional) Use ATCH to attach the PTO0-complete event (event 28) to an interrupt
routine to respond in real time to a PTO0-complete event.
5) Execute the PLS instruction to configure PTO0 and start it.
3.2.4.2.4 PWM Operations
Following takes PWM0 as an example to introduce how to configure and operate the
PTO/PWM generator in the user program.
There are two procedures for using PWM: 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.

Execute PWM
1) Set control byte SMB67 according to the desired operation.
