@ -83,6 +83,8 @@ APIs related to deep sleep and watchdog timer are available in the `ESP` object,
`ESP.deepSleep(microseconds, mode)` will put the chip into deep sleep. `mode` is one of `WAKE_RF_DEFAULT`, `WAKE_RFCAL`, `WAKE_NO_RFCAL`, `WAKE_RF_DISABLED`. (GPIO16 needs to be tied to RST to wake from deepSleep.)
`ESP.rtcUserMemoryWrite(&data, sizeof(data))` and `ESP.rtcUserMemoryRead(&data, sizeof(data))` allow struct data with the maximum size of 512 bytes to be stored and retrieved from the RTC user memory of the chip respectively. The stored data can be retained between deep sleep cycles. However, the data might be lost after power cycling the chip.
`ESP.restart()` restarts the CPU.
`ESP.getResetReason()` returns String containing the last reset resaon in human readable format.
