18.2.3.7 RAMA - RAM Counter Block Access Register
Access:
Address:
RAM counter block contains 12 counter blocks (one for each port) Port 0 counter block starts at address 0.)
The size of each block is 16 double words, which holds, in total, 30 statistic counters. The size and type of
each counter is referred to the register ECR4.
CPU uses this register to access the specified statistic counter by setting the start address of RAM counter
block and the length.
