| DEBOUNCE_ALGO | Description | What to do |
| ------------- | --------------------------------------------------- | ----------------------------- |
| Not defined | You are using the included matrix.c and debounce.c | Nothing. Debounce_sym_g will be compiled, and used if necessary |
-| manual | Use your own debounce.c | ```SRC += debounce.c``` add your own debounce.c and implement necessary functions |
+| custom | Use your own debounce.c | ```SRC += debounce.c``` add your own debounce.c and implement necessary functions |
| sym_g / eager_pk | You are using the included matrix.c and debounce.c | Use an alternative debounce algorithm |
**Regarding split keyboards**:
The debounce code is compatible with split keyboards.
# Use your own debouncing code
-* Set ```DEBOUNCE_ALGO = manual```.
+* Set ```DEBOUNCE_TYPE = custom ```.
* Add ```SRC += debounce.c```
* Add your own ```debounce.c```. Look at included ```debounce_sym_g.c```s for sample implementations.
* Debouncing occurs after every raw matrix scan.
+* Use num_rows rather than MATRIX_ROWS, so that split keyboards are supported correctly.
# Changing between included debouncing methods
You can either use your own code, by including your own debounce.c, or switch to another included one.
