16.5 Super Mapper Register Address Mapping
Each of the Super Mapper’s major functional blocks is selected with an address mapping of the highest order nib-
ble, device pins ADDR[19:16], and allocated a 16-bit address range, pins ADDR[15:0], as defined in
Table 521. Super Mapper Register Address Mapping
16.6 Performance Monitoring (PM) Counters Operation
PM counters are error counters or other statistics counters. In general, two internal registers are needed to imple-
ment a PM counter: a running count register (1), maintained by the core logic, which is incremented by 1, every
time an error (or statistics event) happens. At a defined interval, one second for example, the content of the running
counter is transferred to a holding register (2), while the running count register is reset to 0 and starts to count
anew. The count holding register holds the data that microprocessor actually reads.
