Part Number: AM6442

Hi,

Could you please clarify the maximum GPIO toggle frequency supported on AM6442? Are there any constraints based on clock configuration

Thanks & Regards,

Hello Rubigaa

Thank you for the query.

Please share the use case.

The toggle frequency of GPIO has use case and, loading and software dependensy.

Hi Sreenivasa,

Thank you for the response.

The use case is not to generate a continuous high‑speed clock, but to understand the practical and supported limits of GPIO toggle frequency on AM6442 for debugging and control purposes.

We understand that GPIO toggle frequency depends on software execution path and CPU/system load. Our intent is to understand the typical or recommended maximum practical toggle frequency for AM6442 system GPIOs.

Thanks,

Rubigaa

Hello Rubigaa

Thank you.

for the use case, i suspect the toggle frequency is dependent on the software.

The supported min width is part of the data sheet and added above.
