The HW supports only storing 15 keys at a time. This limits the number of tfms that can work without failutes. Reserve keyslots to solve this and use the reserved ones during the encryption/decryption operation. This allow users to have the capability of hardware protected keys and faster operations if there are limited number of tfms while not halting the operation if there are more tfms.
