SmartFusion2 Micro controller Subsystem (MSS) e fana ka li-peripheral tse thata tsa MMUART (APB_0 le APB_1 libese tse nyane) tse nang le Full/Half Duplex, Asynchronouss/ Synchronous mode le khetho ea interface ea Modem.
Ho MSS Canvas, o tlameha ho bulela (ea kamehla) kapa o tima ketsahalo e 'ngoe le e 'ngoe ea MMUART ho latela hore na e ea sebelisoa ts'ebelisong ea hau ea hajoale. Maemo a holofetseng a MMUART a ts'oaroe a setiloe bocha (maemo a tlase a matla). Ka linako tsohle, likou tsa maemo a MMUART tse lumelletsoeng li lokiselitsoe ho hokela sesebelisoa sa Multi Standard I/Os (MSIOs). Hlokomela hore li-MSIO tse abetsoeng ketsahalo ea MMUART li arolelanoa le lisebelisoa tse ling tsa MSS. Li-I/O tsena tse arolelanoang lia fumaneha ho hokela ho MSS GPIOs le lisebelisoa tse ling ha mohlala oa MMUART o koetsoe kapa haeba likou tsa mohlala tsa MMUART li hokahane le lesela la FPGA.
