The STM32H7 series drive SDRAM by fmc,
Which is maximum sdram frequency 100Mhz or 200Mhz can run?
There are four input clock sources for fmc_ker_ck, and SDRAM clock can be fmc_ker_ck/2 or fmc_ker_ck/3.
If I choose clock source "pll1_q_ck" (max=400Mhz), then SDRAM can run -5 (200Mhz)?
Or it only can choose "bus_clocks" (max=200Mhz), then SDRAM run -10 (100Mhz)?
