By default, the value is 0 meaning that only the 77 physical clock is in use. Setting the value creates 78 the corresponding number of virtual clocks and causes 79 the physical clock to become free running. Setting the 80 value back to 0 deletes the virtual clocks and 81 switches the physical clock back to normal, adjustable 82 operation. 83 |
