 * Memory Access Events

 *
 * MMCRA bits encoding needed are
 *     SM (Sampling Mode)
 *     EM (Eligibility for Random Sampling)
 *     TECE (Threshold Event Counter Event)
 *     TS (Threshold Start Event)
 *     TE (Threshold End Event)

 * Corresponding Raw Encoding bits:

 *     thresh_sel (TECE)
 *     thresh start (TS)
