Configuration
1. Update the template version to the required version:
2. Configure the key.
The expansion key should be configured starting after the final regular DSS key.
For example, T53 support 21 regular DSS keys. To configure the expansion module. User needs to configure the 22nd key. The key started from 22nd are all for expansion module.
Also a note, the blank key(meaning type is selected as null) is allowed to exist between key 1 and key 22.
A extreme condition that you dont' configure any regular DSS key. You have to configure 21 blank keys, then configure the expand module from 22nd key.
3. Expansion Key mapping.
