When operating from STM32H745 to Timer Interrupt, ...

- MCU : STM32H745

- NAND Flash Memory: W29N02GV

- STM32H7xx HAL Driver version number : V1.6.0

Using STM32H745 FMC to NAND Flash Memory during operation test, Error on write NAND Flash if Timer Interrupt 1KHz is set above, Normal operation on write NAND Flash if Timer Interrupt setting is less than 1KHz.

1. In NAND Flash FMC setting, ComSpaceTiming, AttSpaceTiming can this happen if something goes wrong?

2. Is there a reference for the calculation method of NAND Flash ComSpaceTiming, AttSpaceTiming?

3. Does it affect setting CPU Cache(ICache, DCache) Disabled?
