What are the different values for the ESP32-S2 UART_PRINT_CONTROL eFuse?

The ESP32-S2 UART_PRINT_CONTROL eFuse controls the behavior of the UART print output during the ROM boot phase. According to ESP-IDF on GitHub, it consists of two bits:

Burning it can not be undone, but if you really want to do it, here’s an example of how to burn it to 0b11:

espefuse.py burn_efuse UART_PRINT_CONTROL 0b11

This will ask you for confirmation before proceeding with the burn operation.

espefuse.py v4.9.0
Connecting...
Device PID identification is only supported on COM and /dev/ serial ports.
.
Detecting chip type... Unsupported detection protocol, switching and trying again...
Detecting chip type... ESP32-S2

=== Run "burn_efuse" command ===
The efuses to burn:
  from BLOCK0
     - UART_PRINT_CONTROL

Burning efuses:

    - 'UART_PRINT_CONTROL' (Set the default UART boot message output mode) 0b00 -> 0b11


Check all blocks for burn...
idx, BLOCK_NAME,          Conclusion
[00] BLOCK0               is empty, will burn the new value

This is an irreversible operation!
Type 'BURN' (all capitals) to continue.
