| Choose which clock is used as RTC clock source. |
| |
| - "Internal 150kHz oscillator" option provides lowest deep sleep current |
| consumption, and does not require extra external components. However |
| frequency stability with respect to temperature is poor, so time may |
| drift in deep/light sleep modes. |
| - "External 32kHz crystal" provides better frequency stability, at the |
| expense of slightly higher (1uA) deep sleep current consumption. |
| - "External 32kHz oscillator" allows using 32kHz clock generated by an |
| external circuit. In this case, external clock signal must be connected |
| to 32K_XN pin. Amplitude should be <1.2V in case of sine wave signal, |
| and <1V in case of square wave signal. Common mode voltage should be |
| 0.1 < Vcm < 0.5Vamp, where Vamp is the signal amplitude. |
| Additionally, 1nF capacitor must be connected between 32K_XP pin and |
| ground. 32K_XP pin can not be used as a GPIO in this case. |
| - "Internal 8.5MHz oscillator divided by 256" option results in higher |
| deep sleep current (by 5uA) but has better frequency stability than |
| the internal 150kHz oscillator. It does not require external components. |

| When the startup code initializes RTC_SLOW_CLK, it can perform |
| calibration by comparing the RTC_SLOW_CLK frequency with main XTAL |
| frequency. This option sets the number of RTC_SLOW_CLK cycles measured |
| by the calibration routine. Higher numbers increase calibration |
| precision, which may be important for applications which spend a lot of |
| time in deep sleep. Lower numbers reduce startup time. |
| |
| When this option is set to 0, clock calibration will not be performed at |
| startup, and approximate clock frequencies will be assumed: |

| - 150000 Hz if internal RC oscillator is used as clock source. For this use value 1024. |
| - 32768 Hz if the 32k crystal oscillator is used. For this use value 3000 or more. |

| help |
| When ESP32 exits deep sleep, the CPU and the flash chip are powered on |
| at the same time. CPU will run deep sleep stub first, and then |
| proceed to load code from flash. Some flash chips need sufficient |
| time to pass between power on and first read operation. By default, |
| without any extra delay, this time is approximately 900us, although |
| some flash chip types need more than that. |
| |
| By default extra delay is set to 2000us. When optimizing startup time |
| for applications which require it, this value may be reduced. |
| |
| If you are seeing "flash read err, 1000" message printed to the |
| console after deep sleep reset, try increasing this value. |

| help |
| Configure the number of universally administered (by IEEE) MAC addresses. |
| During initialization, MAC addresses for each network interface are generated or |
| derived from a single base MAC address. If the number of universal MAC addresses is four, |
| all four interfaces (WiFi station, WiFi softap, Bluetooth and Ethernet) receive a universally |
| administered MAC address. These are generated sequentially by adding 0, 1, 2 and 3 (respectively) |
| to the final octet of the base MAC address. If the number of universal MAC addresses is two, |
| only two interfaces (WiFi station and Bluetooth) receive a universally administered MAC address. |
| These are generated sequentially by adding 0 and 1 (respectively) to the base MAC address. |
| The remaining two interfaces (WiFi softap and Ethernet) receive local MAC addresses. |
| These are derived from the universal WiFi station and Bluetooth MAC addresses, respectively. |
| When using the default (Espressif-assigned) base MAC address, either setting can be used. |
| When using a custom universal MAC address range, the correct setting will depend on the |
| allocation of MAC addresses in this range (either 2 or 4 per device.) |
