SmartFusion2 Microcontroller Subsystem (MSS) e fana ka GPIO hard peripheral (APB_1 sub bese) e tšehetsang 32 General Purpose I/Os.
Ho canvas ea MSS, u tlameha ho bulela (ea kamehla) kapa u tima mohlala oa GPIO ho latela hore na e sebelisoa ts'ebelisong ea hau ea hajoale. Haeba e holofalitsoe, mohlala oa GPIO o tla ts'oaroa hape (maemo a tlase a matla). Ka kamehla, ha ho na GPIO e sebelisoang ha u nolofalitse mohlala oa GPIO lekhetlo la pele. Hlokomela hore li-MSIO tse abetsoeng mohlala oa GPIO li arolelanoa le lisebelisoa tse ling tsa MSS. Li-I/O tsena tse arolelanoang lia fumaneha ho hokahanya lisebelisoa tse ling ha mohlala oa GPIO o holofetse kapa haeba likou tsa mohlala tsa GPIO li hokahane le lesela la FPGA.
