Resolved! Decoding the STM32H563 datasheet (RM0481 rev 1)

The MCU is great, but the datasheet (in particular the SPI section) is very hard to read. Whatever the original language was, it wasn't English, and I guess Google translate has been involved. I've added an example below, and hope for ST to update th...
