Disable Digital Outputs via FCCU on MPC5744P

Regarding MPC5744P the Safety Manual states the following: "When the FCCU intends to drive FCCU_F[0] to a fault condition, the SIUL2 disables the output buffer of such pins for which SIUL2_MSCRn[SMC] is cleared ...". The Safety Manual mentions this as a possibility only for pins that are associated with communication controllers, like CAN. But what happens if SIUL2_MSCRn[SMC] is cleared for a Digital Out pin? Will it be forced to tri-state/high-z/floating state?
