# This files is the source of truth what features (as build system entities)
# exist in RIOT. The file `makefiles/features_existing.inc.mk` is generated
# from this list, and so is the documentation in
# `doc/doxygen/src/feature_list.md`. To regenerate them, run
# `make generate-features` in the root of the repo.
#
# The syntax is relatively simple: A group is a mapping that may contain a
# string-valued "title" and "help", may contain a list of groups under the
# "groups" key, and a list of features under the "features" key, where a
# feature is expressed as a mapping that contains a "name" and a "help" string.
# The syntax is formally described in dist/tools/features_yaml2mx/schema.cddl.
#
# Note: The syntax or even the file format will likely change and evolve over
# time.

transfer is completed. It often also speeds up longer transfers.

lower power modes via GPIO, but it is currently the only MCU were
this feature is configurable.
- title: GPIO LL API
help: This is a lower level GPIO API that allows port based access. It
exposes a number of advanced features and lower latency GPIO
access at the cost of a more complex and more frequently
changing API. You should only use this if the Pin Level Peripheral
GPIO API is not catering your use case well enough.

the GPIO is configured in input mode.
- name: periph_gpio_ll_open_drain

help: Some or all pins can be configured in open source mode.
- name: periph_gpio_ll_open_source_pull_down
help: Some or all GPIO pins can enable an internal pull down resistor when
the GPIO is configured in open source mode.
- name: periph_gpio_ll_switch_dir
help: The GPIO LL driver allows switching the direction between input
and (push-pull) output in an efficient manner. The main use case
is bit-banging bidirectional protocols when open-drain / open-source
mode is not supported. GPIO LL drivers for peripherals that do
support open drain mode typically do not bother implementing this,
even if the hardware would allow it.
