NO FMC_SDNCAS alternate function info in

[sheng yang]

I want to design a baord with stm32h7b0zbt6 with extranal sdram chip W9825G6KH-6. I get PG15 with FMC_SDNCAS alt func in datasheet as below:

But when I looked the PG15 alt func config I get as below info, I could not found an alternate function number for FMC_SDNCAS here ?? why they are not consistent ?

Hello,

Most probably it's a miss in table 14. By analogy with STM32H743 PG15 has FMC_SDNCAS alternate function.

The internal ticket 178406 has been submitted to confirm and fix the issue.

I will keep you informed for any feedback.
