+# Embassy MSPM0 HAL
+
+The embassy-mspm0 HAL aims to provide a safe, idiomatic hardware abstraction layer for all MSPM0 and MSPS003 chips.
+
+* [Documentation](https://docs.embassy.dev/embassy-mspm0/) (**Important:** use docs.embassy.dev rather than docs.rs to see the specific docs for the chip you’re using!)
+* [Source](https://github.com/embassy-rs/embassy/tree/main/embassy-mspm0)
+* [Examples](https://github.com/embassy-rs/embassy/tree/main/examples)
+
+## Embedded-hal
+
+The `embassy-mspm0` HAL implements the traits from [embedded-hal](https://crates.io/crates/embedded-hal) (1.0) and [embedded-hal-async](https://crates.io/crates/embedded-hal-async), as well as [embedded-io](https://crates.io/crates/embedded-io) and [embedded-io-async](https://crates.io/crates/embedded-io-async).
+
+## A note on feature flag names
+
+Feature flag names for chips do not include temperature rating or distribution format.
+
+Usually chapter 10 of your device's datasheet will explain the device nomenclature and how to decode it. Feature names in embassy-mspm0 only use the following from device nomenclature:
+- MCU platform
+- Product family
+- Device subfamily
+- Flash memory
+- Package type
+
+This means for a part such as `MSPM0G3507SPMR`, the feature name is `mspm0g3507pm`. This also means that `MSPM0G3507QPMRQ1` uses the feature `mspm0g3507pm`, since the Q1 parts are just qualified variants of the base G3507 with a PM (QFP-64) package.
+
+## Interoperability
+
+This crate can run on any executor.
