If my understanding is correct, I think this question is fully answered in Table 3-8 "SPI Signal configuration" of the LS1043A Reference Manual.


Have a great day,
Alexander

I understand i need to keep SPI_BASE[382-383] as 00, But i'm confused with what value should i keep on SPI_EXT[360-362]. Please suggest me the SPI_EXT[360-362] bit value such that i can use the remaining chip selects as GPIOs
