Question: What are the clock sources for watchdog timer in FX3?
Answer: There are two options, which are selected by CyU3PSysClockConfig_t field in CyU3PDeviceInit API.
1. External 32KHz oscillator,
2. Internal oscillator,
If you are using internal oscillator as the clock source for watchdog timer then it can’t be used as a wakeup source in standby mode, because in this power mode the internal oscillator will be turned off.
