Available licenses = licenses to be picked up - new picked-up licenses
That is, the maximum quantity of new licenses that you can download is the quantity to be picked up in the original order. If you have already picked up some new licenses, the quantity shall be deducted.
For example, if you place a license order for 1,000 licenses, 600 of which have been picked up, now you want to download new licenses to flash into the module, you can pick up 600 licenses at most. You can pick up the left licenses many times in any quantity. If you pick up the left 400 licenses, you can pick up 400 more new licenses.
