HI I need to know the pin names for motor controller PWM out

PWM High and PWM LOW

i can not directly PWM out function for pins

Also need capture control pin details to measure the PWM.

As i have to assign these pins for controller

STM32G4 series

eg, for the High Resolution Timer (HRTIM):

have you also looked at Application Note AN4013, Introduction to timers for STM32 MCUs:

All the pin names & Alternate Functions are listed in the chip's datasheet.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

TIM17_BKIN,
USB_CRS_SYNC,
I2C2_SMBA,
SPI2_MISO,
TIM1_CH3,
USART1_RX,
COMP6_OUT,
TIM2_CH4,
TIM8_BKIN, SAI1_D1,
SAI1_SD_A,
EVENTOUT

Where is the PWMout from above alternate fucntions?

or how can check CCP for pwm measurement

You'll also need to look in the Timer descriptions in the Reference Manual - that'll tell you what Alternate Functions are used ...
