How to enable the FlexPWM driver setting based on the pwm pin configuration on spc5 board?

[Angle]

Hi, can anyone explain to me about this FlexPWM driver?

What is SM0 stand for? and how i can set the driver based on pin configuration? i did not understand about this setting.

Let say i want to configure pin on PORT_E[5] which is PWM_0/A1_0. So, in this setting which one i need to tick to enable the driver?

Hello,

assuming that your MCU version is a SPC574S

and looking into the corresponding reference manual (motor control -> FlexPWM):

https://www.st.com/resource/en/reference_manual/rm0387-spc574sx-32bit-power-architecture-microcontroller-for-automotive-asild-applications-stmicroelectronics.pdf

it seems that SM0 stands for SubModule0 of a PWM module

In your case, using pin Port_E[5] , the A1_0 configuration is linked to the SM1 of PWM0

So in SPC5Studio, you need to enable at least FlexPWM0 SM1:

hen it will enable the driver FLEXPWMD2:

Okay then may i know how i can recognize whether it its SM0, SM1, SM2 or SM3? I got confuse for this SM0, SM1, SM2, SM3

I was confused too before to look at the PWM block diagram in the reference manual.

Please open the RM and look to Figure 419. PWM Block Diagram
