acceptance filter

The acceptance filter in CAN controller chips is used to select messages that are received depending on the assigned identifier. Most of the CAN controller chips provide a hardware acceptance filter that filters CAN messages assigned with a specific identifier or a range of identifiers. The user-settable filter unburdens the micro-controller from the task of acceptance filtering.
