By default, Development mode is enabled which allows ROM download mode to perform Flash Encryption
operations (plaintext is sent to the device, and it encrypts it internally and writes ciphertext
to flash). This mode is not secure, it's possible for an attacker to write their own chosen plaintext
to flash.
Release mode should always be selected for production or manufacturing. Once enabled it's no longer
possible for the device in ROM Download Mode to use the Flash Encryption hardware.

Set the number of WiFi dynamic RX buffers, 0 means unlimited RX buffers will be allocated

the received data frame.
For each received data frame, the WiFi driver makes a copy to an RX buffer and then delivers
it to the high layer TCP/IP stack. The dynamic RX buffer is freed after the higher layer has
successfully received the data frame.
For some applications, WiFi data frames may be received faster than the application can
process them. In these cases we may run out of memory if RX buffer number is unlimited (0).
If a dynamic RX buffer limit is set, it should be at least the number of static RX buffers.

delivered to the Wifi driver from the TCP/IP stack. The buffer is freed after the data frame
has been sent by the WiFi driver. The size of each dynamic TX buffer depends on the length
of each data frame sent by the TCP/IP layer.

---help---
Wi-Fi supports the Modem-sleep mode which refers to the legacy power-saving mode in the IEEE 802.11 protocol.
Modem-sleep mode works in station-only mode and the station must connect to the AP first. If the Modem-sleep
mode is enabled, station will switch between active and sleep state periodically. In sleep state, RF, PHY and
BB are turned off in order to reduce power consumption. Station can keep connection with AP in modem-sleep mode.
Modem-sleep mode includes minimum and maximum power-saving modes.
In minimum power-saving mode, station wakes
up every DTIM to receive beacon. Broadcast data will not be lost because it is transmitted after DTIM.
However, it cannot save much more power if DTIM is short for DTIM is determined by AP.
In maximum power-saving mode, station wakes up in every listen interval to receive beacon. This listen interval
can be set to be longer than the AP DTIM period. Broadcast data may be lost because station may be in sleep
state at DTIM time. If listen interval is longer, more power is saved, but broadcast data is more easy to lose.
Listen interval can be configured by setting ESPRESSIF_WIFI_LISTEN_INTERVAL.
ESPRESSIF_POWER_SAVE_NONE disables Modem-sleep mode entirely. Disabling it increases power consumption, but
minimizes the delay in receiving Wi-Fi data in real time. When Modem-sleep mode is enabled, the delay in
receiving Wi-Fi data may be the same as the DTIM cycle (minimum power-saving mode) or the listening interval
(maximum power-saving mode). Setting ESPRESSIF_POWER_SAVE_NONE is suitable when high throughput is required.

- "External 32KHz crystal" provides better frequency stability, at the

- "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

Additionally, 1nF capacitor must be connected between 32K_XP pin and
