Setting PKTCTRL1.ADR_CHK to any othervalue than zero enables the packet addressfilter. The packet handler engine will comparethe destination address byte in the packet withthe programmed node address in the ADDRregister and the 0x00 broadcast address whenPKTCTRL1.ADR_CHK=10 or both 0x00 and0xFF broadcast addresses whenPKTCTRL1.ADR_CHK=11. If the receivedaddress matches a valid address, the packet isreceived and written into the RX FIFO. If theaddress match fails, the packet is discardedand receive mode restarted (regardless of theMCSM1.RXOFF_MODE setting).
