//! Watchdog drivers.
//!
//! The `RA4M1` has two watchdog timers available for use: Independent Watchdog Timer ([`IWDT`](iwdt)) and Watchdog Timer ([`WDT`](wdt)).
//! `IWDT` is driven by a wholly independent clock and can only be configured at reset-time via `OSM`.
//! `WDT` is driven by [`PCLKB`](struct@crate::clock::ClockStatus) and can be configured either at reset-time via `OSM` or at runtime via its registers.
