Hi everyone,

Thanks for helping

Hi,

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.
