This read-create RowStatus value governs adding and clearing clock-source entries in the clock-input management table: adding a source puts the clock in trace mode, while clearing it reverts to crystal mode, and the position/oper fields must be set together for certain operations. Admins use it to provision or remove a physical or logical clock source entry from the device's timing configuration. For example, an admin configuring a new BITS clock source would set hwClkInRowStatus alongside the frame/slot/port fields to add that entry to the table.
