HRTIM output is not observed as mentioned in datasheet

[FEngi.1]

Hello Team,

I would like to mention an error I’m facing while testing the HRTIM module in STM32G474RE Evaluation Board. Please find the error details below.

Evaluation Board Used: STM32G474RE

Issue details:

In the STM32datasheet: stm32g474ce_details.pdf (page no: 843, attached), various cases are mentioned on HRTIM Set/Reset

1st case

• Case mentioned in datasheet: When (Reset/set with delay < tHRTIM) we should observe a pulse of width tHRTIM with Reset been shifted to reach the tHRTIM width.
• Scenario Tested:
• fHRTIM = 170Mhz
• period = 4096 (Multiple of 32)
• CMP1xR = 156
• CMP2xR = 162
• Observation: No response as output

2nd case

• Case mentioned in datasheet: When (Reset/set with delay < tHRTIM) we should observe a pulse of width tHRTIM with Reset been shifted to reach the tHRTIM width.
• Scenario Tested:
• fHRTIM = 170Mhz
• period = 4096 (Multiple of 32)
• CMP1xR = 154
• CMP2xR = 164
• Observation: Received output but not having the width of tHRTIM

Please find the attached project which was used for testing. Also please let me know if I’m doing anything wrong here or my understanding is wrong as my observations are not matching with those mentioned in datasheet

Hoping to hear from you soon.
