Iziko leNkxaso yoBugcisa boMthengi
Iqela leeMveliso ze-Microsemi SoC lisebenza kwiZiko leNkxaso yoBugcisa boMthengi kunye neenjineli ezinezakhono eziphezulu ezinokukunceda ukuphendula i-hardware yakho, isofthiwe, kunye nemibuzo yoyilo malunga neeMveliso ze-Microsemi SoC. Iziko leNkxaso yoBugcisa boMthengi lichitha ixesha elininzi lidala amanqaku ezicelo, iimpendulo kwimibuzo yomjikelo woyilo oluqhelekileyo, uxwebhu lwemiba eyaziwayo, kunye nee-FAQ ezahlukeneyo. Ke, ngaphambi kokuba uqhagamshelane nathi, nceda undwendwele izixhobo zethu ze-intanethi. Kusenokwenzeka ukuba sele siyiphendulile imibuzo yakho.
Uxhaso lobuchwepheshe
Ndwendwela iNkxaso yoMthengi webindawo (www.microsemi.com/soc/support/search/default.aspx) ngolwazi oluthe kratya kunye nenkxaso. Iimpendulo ezininzi ziyafumaneka kwiphendla web izibonelelo zibandakanya imizobo, imizobo, kunye namakhonkco kwezinye izixhobo kwi webindawo.
