I want to configure a SDRAM in a stm32h743iit6 custom board.
but question is where can I can set the clock of FMC, from below section?
if I set it on 240MHz then the SDCLK Pin supply SDARAM with 240MHz or half of it? or should set with another parameter?
Furthermore the clock frequency of SDRAM is 133Mhz or 143MHz:
but probably I will force to set the frequency at lower. could it cause any problem?
and finally... what is "SDRAM common clock"?
it should be calculated by tRDD or tCKED or ... ?
sorry for my bad english.
