 - `Double Reset` Reset twice within 500 ms will enter DFU with UF2 and CDC support (only works with nRF52840)
 - `DFU = LOW` and `FRST = HIGH`: Enter bootloader with UF2 and CDC support
 - `DFU = LOW` and `FRST = LOW`: Enter bootloader with OTA, to upgrade with a mobile application such as Nordic nrfConnect/Toolbox
-- `DFU = HIGH and `FRST = LOW`: Factory Reset mode: erase firmware application and its data
-- `DFU = HIGH and `FRST = HIGH`: Go to application code if it is present, otherwise enter DFU with UF2
+- `DFU = HIGH` and `FRST = LOW`: Factory Reset mode: erase firmware application and its data
+- `DFU = HIGH` and `FRST = HIGH`: Go to application code if it is present, otherwise enter DFU with UF2
 - The `GPREGRET` register can also be set to force the bootloader can enter any of above modes (plus a CDC-only mode for Arduino).
 `GPREGRET` is set by the application before performing a soft reset.
