70 Control Information (Continued)
Counter Increment Latch Register (CILR)
The Counter Increment Latch Register (CILR) records the occurrence of any increment to the SMT Counters in the Ring Engine
Each bit corresponds to a counter and is set when the corresponding counter is incremented Each bit may be masked via the
Counter Increment Mask Register (CIMR)
