When configured as a specific low power state: MFP_LPM_DRIVE_LOW, MFP_LPM_DRIVE_HIGH, the corresponding GPDR register bit during low power mode shall be re-configured as output (if they are not configured so), thus the PGSRx bits can output. Create an additional low power values GPDR registers, and properly save/restore the GAFR + GPDR registers when doing suspend/resume.
