Zarlink Semiconductor Inc.
MIRROR1_DEST: Sets the destination port for the first port mirroring pair. Bits [4:0] select the destination port to be
mirrored. The default is port 23.
MIRROR2_SRC: Sets the source port for the second port mirroring pair. Bits [4:0] select the source port to be
mirrored. An illegal port number is used to disable mirroring (which is the default setting). Bit [5] is used to select
between ingress (Rx) or egress (Tx) data.
MIRROR2_DEST: Sets the destination port for the second port mirroring pair. Bits [4:0] select the destination port to
be mirrored. The default is port 0.

Hardware Statistics Counters List
ZL50418 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.
