## Detailed Description

MOST\_HWMODE.

This event is fired when one or more HW state changes. HW states are the AllBypass bit (e.g. ABY of OS8104), the Master/Slave selection (e.g. MTR of OS8104), the Control spy and the Asynchronous spy. The event transports all states even if only a single state has changed. hwModeMask denotes which state differs regarding to the previous HW mode event.
