Note: Each port owns a counter block, containing 16 double words. The 29 bits indicate that each corresponding
counter is wrapping around the signal. The type and location of each counter is specified by the following format.
The format description:
X-Y: X means the relative Physical Address in its counter blocks.
: Y indicates the type of counter it is (Notation “C”= double word read from RAM block)
D: C[31:0] double word counter
L: C[23:0] 24 bits counter
U: C[31:24] 8 bits counter
U1: C[23:16] 8 bits counter
U2: C[31:24] bits counter (the same as notation “U”)
l: C[15:0] 16 bits counter
u C[31:16] 16 bits counter
