-- `ESP8266_MAX_DELAY_TIME_MS`: The maximum time in milliseconds the CPU will be delayed while no task is scheduled. Default is infinite. Set this value if you expect interrupts while no task is running.
+- `ESP8266_MAX_DELAY_TIME_MS`: The maximum time in milliseconds the CPU will be delayed while no task is scheduled. Default is 7000 due to the watchdog timeout of 8 seconds. Set this value lower if you expect interrupts while no task is running.
