Nuvoton NPCM SGPIO module is combine serial to parallel IC (HC595) and parallel to serial IC (HC165), and use APB3 clock to control it. This interface has 4 pins (D_out , D_in, S_CLK, LDSH). NPCM7xx/NPCM8xx have two sgpio module each module can support up to 64 output pins,and up to 64 input pin, the pin is only for GPI or GPO. The NPCM SGPIO patchset is on upstream process.
