10.0 Hardware Statistics Counter
10.1 Hardware Statistics Counters List
MVTX2802AG hardware provides a full set of statistics counters for each Ethernet port. The CPU accesses
these counters through the CPU interface. All hardware counters are rollover counters. When a counter rolls
over, the CPU is interrupted, so that long-term statistics may be kept. The MAC detects all statistics, except for
the delay exceed discard counter (detected by buffer manager) and the filtering counter (detected by queue
manager). The following is the wrapped signal sent to the CPU through the command block.
Bits [2:0]
Signal select:
0: do not select
1: select the corresponding bit
The value of LED_BYTEOUT_[0] equals the logical OR of all selected bits.
