choice ESP32C5_UNIVERSAL_MAC_ADDRESSES
bool "Number of universally administered (by IEEE) MAC address"
default ESP32C5_UNIVERSAL_MAC_ADDRESSES_FOUR
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.)
Note that ESP32-C5 has no integrated Ethernet MAC. Although it's possible to use the esp_read_mac()
API to return a MAC for Ethernet, this can only be used with an external MAC peripheral.

help
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:
- 136000 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.
In case more value will help improve the definition of the launch of the crystal.
If the crystal could not start, it will be switched to internal RC.
