It cannot be directly configured by the ASA administrator. It should come up only if you are actively using a Firepower service module as it moves data internally to/from the module's management interface.

How many internal interfaces there are depends on the platform. Following is output taken from an ASA 5555-X with Firepower services module:

# show interface detail | i Internal- Interface Internal-Control0/0 "cplane", is up, line protocol is up Interface Internal-Data0/0 "asa_mgmt_plane", is up, line protocol is up Interface Internal-Data0/1 "", is up, line protocol is up Interface Internal-Data0/2 "mgmt_plane_int_tap", is up, line protocol is up Interface Internal-Data0/3 "nlp_int_tap", is up, line protocol is up #
