1//! Module stop (`MSTP`).
2//!
3//! The `RA4M1` supports clock gating via four (4) "module stop" registers.
4//! After reset only the `DMAC`, `DTC`, and `SRAM` peripherals are enabled.
5//! To enable additional peripherals use the `start_module` function.
6//!
7//! # Notes
8//! - Some peripheral instances (e.g. `GPT`) share the same gate.
9//! - See §10.4.
