-It has four mapped register accepting only writes.
+It has six mapped register: 5 accepting only writes, and one accepting only reads.
 
 Possible actions are:
  * Make the simulator call `sc_stop()`
- * Make the simulator call `exit( val )`, with a given `val`
+ * Make the simulator call `exit(val)`, with a given `val`
  * Make the simulator throw an exception with a given value in message
+ * Make the simulator raise the interrupt signal SIGINT
  * Make the simulator pause (i.e. wait for a keyboard event)
+ * Make the simulator return the number of cycles of simulation

  * `SIMHELPER_SC_STOP` (at offset 0x0): Call `sc_stop()`
