Which register can set the timeout for the FMC's NWAIT signal to prevent a crash?

[Andy_Zhou]

Hi

Chip：stm32h723

Peripheral:FMC

Configuration:FMC_NORSRAM_DEVICE , FMC_NORSRAM_EXTENDED_DEVICE;

FMC_ACCESS_MODE_A

FMC_ASYNCRONOUS_WAIT_ENABLE

If the extended device(eg. FPGA) do not assert NWAIT，the program on stm32h723 will crash. I want to know which register can set the timeout for the NWAIT signal to prevent a crash?

Best regards,

Andy Zhou

Hello,

Unfortunately, there is no way to recover from that situation except to reset the CPU for example using the watchdog.
