This setting is not changed when re-initializing the EEPROM using the `EEP_RST` key, or using the `eeconfig_init()` function. However, if you reset the EEPROM outside of the firmware's built in options (such as flashing a file that overwrites the `EEPROM`, like how the [QMK Toolbox]()'s "Reset EEPROM" button works), you'll need to re-flash the controller with the `EEPROM` files.

```
This sets the poll frequency when detecting master/slave when using `SPLIT_USB_DETECT`
```c
#define SPLIT_WATCHDOG_ENABLE
```
This will enable a software watchdog on any side delegated as slave and will reboot the keyboard if no successful communication occurs within `SPLIT_WATCHDOG_TIMEOUT`. This can be particularly helpful when `SPLIT_USB_DETECT` delegates both sides as slave in some circumstances.
```c
#define SPLIT_WATCHDOG_TIMEOUT 3000
```
This set the maximum slave timeout when waiting for communication from master when using `SPLIT_WATCHDOG_ENABLE`
## Hardware Considerations and Mods
Master/slave delegation is made either by detecting voltage on VBUS connection or waiting for USB communication (`SPLIT_USB_DETECT`). Pro Micro boards can use VBUS detection out of the box and be used with or without `SPLIT_USB_DETECT`.
