| This hidden option is set in the board configuration and indicates |

| When the virtual CPU is sleeping, the virtual time will advance |
| at default speed unless this option is set. With this option set, |
| the virtual time will jump to the next timer deadline instantly |
| whenever the virtual CPU goes to sleep mode and will not advance |
| if no timer is enabled. This behavior gives deterministic execution |
