SM8212B Features

* a built-in filter. Each of the addresses (max. 8) can be assigned to any frame, which also makes the device configurable for many additional services. Each address can be independently set ON/OFF. Furthermore, built-in buffer memory means decoded information can be fetched in sync with the microcont
