Why does CubeMX only allow SD High Speed in 32L4Rxx and 32L4Sxx?

Question asked by johnston.paul.001 on Nov 17, 2017

I generated the code for a STM32L496 that hopes to use the SDIO with an external SD card. To meet my data throughput, I will need the 4 bit bus and the high speed mode which the L496 appears to have. However, the generated code has restricted these two features to only STM32L4Rxxx and STM32L4Sxxx versions of the chips (using #if defined...).


What am I missing?
