STM32H7 errata sheet rev13 : new erratum about SPI not clear

Gpeti

The new revision of errata sheet for STM32H7 mentions a new error relative to SPI:

It is particularly vague.

What "fast software" and "slow SPI" frequency means exactly ? What is the minimum ration between both frequencies to avoid the issue ?

What "add a delay" means ? How many clock cycles ?

With this description it is impossible to evaluate if a software may have this issue neither to implement a workaround.
