+    event index or mask specified by immediate operand.
+
+    Without `mask` it triggers a single performance monitor event indexed by
+    immediate operand a, in the range 0..15.
+
+    With `mask` it triggers one or more of the performance monitor events. Each
+    bit in the 16-bit immediate operand a controls an event.
