9 | BROADCAST_EN | R/W | 0h | Broadcast Enable bit This will enable the reception of a ping frame broadcast. When this bit is set, bit 3 of the received tag will be treated as a broadcast notification. If bit 3 of the received tag is set to 1, a ping tag match event will be triggered regardless of the. A match caused by the comparison of TAG_MASK and TAG_REF will still be considered a match and the frame tag match event will be triggered as normal This bit only takes effect only if CMP_EN is set to 1. 0h[R/W] Broadcast frame match disabled. 1h[R/W] Broadcast frame match enabled. |
8 | CMP_EN | R/W | 0h | Frame Tag Compare Enable bit Set this bit to enable the comparison of an incoming frame tag and the value stored in the frame tag reference. A match caused by the comparison of TAG_MASK, TAG_REF, and the incoming frame tag will trigger the apprpriate frame tag match event. 0h[R/W] Frame tag comparison is disabled. 1h[R/W] Frame tag comparison is enabled. |
7:4 | TAG_MASK | R/W | 0h | Frame Tag Mask Any bit position in this register set to 0 will be used in the comparison of the incoming frame tag and the value stored in TAG_REF. A bit position set to 1 will be ignored in the tag comparison. This mask value is used only for non-ping frames. |
3:0 | TAG_REF | R/W | 0h | Frame Tag Reference The reference tag to check against when comparing the TAG_MASK and the incoming frame tag. This reference value is used only for non-ping frames. |
