Hi everyone,

Thanks for helping

Hi,

on page 27 of the latest FX3APIGuide.pdf you can find the according informations and API's for using the watchdog.

Thanks for your response,

it works. The watchdog resets the device when it is not responsive. Now I have another problem. Where can I read out if a watchdog reset occured. I tried to read this information from register CY_U3P_PIB_PP_INIT but it is always 0x0C01 even if a watchdog reset occured.

Thanks for helping

You will have implement your own mechanism to detect watchdog reset. This can be done by using uninitialized global flag or by storing a flag in SPI/I2C EEPROM.
