RRCSTS=B_0x0, RXQSTS=B_0x0
Rx queue debug register
RWCSTS | MTL Rx Queue Write Controller Active Status When high, this bit indicates that the MTL Rx queue Write controller is active, and it is transferring a received packet to the Rx queue. |
RRCSTS | MTL Rx Queue Read Controller State This field gives the state of the Rx queue Read controller: 0 (B_0x0): Idle state 1 (B_0x1): Reading packet data 2 (B_0x2): Reading packet status (or timestamp) 3 (B_0x3): Flushing the packet data and status |
RXQSTS | MTL Rx Queue Fill-Level Status This field gives the status of the fill-level of the Rx queue: 0 (B_0x0): Rx queue empty 1 (B_0x1): Rx queue fill-level below flow-control deactivate threshold 2 (B_0x2): Rx queue fill-level above flow-control activate threshold 3 (B_0x3): Rx queue full |
PRXQ | Number of Packets in Receive Queue This field indicates the current number of packets in the Rx queue. The theoretical maximum value for this field is 256Kbyte/16bytes = 16K Packets, that is, Max_Queue_Size/Min_Packet_Size. |
