applyNewHardwareSettings()

void applyNewHardwareSettings

this method is NOT currently invoked on ECU start todo: reduce code duplication by moving more logic into startHardware method

All 'stop' methods need to go before we begin starting pins.

We take settings from 'activeConfiguration' not 'engineConfiguration' while stopping hardware. Some hardware is restart unconditionally on change of parameters while for some systems we make extra effort and restart only relevant settings were changes.
