BRD_PWM_COUNT missing

just loaded 4.2.0-dev, the BRD_PWM_COUNT parameter is missing. Do I need to enable it via some other parameter to obtain access?
thanks

BRD_PWM_COUNT was removed recently. See https://github.com/ArduPilot/ardupilot/pull/18018 for details.

Great, thank you for letting me know that seems like an improvement
