Struct Pac

pub struct Pac { /* private fields */ }

Collection of low-level PAC structs

This struct serves to guard access to the low-level PAC structs. It places them behind an unsafe barrier.

Normally, users trade the low-level PAC structs for the higher-level clock::v2 API. However, in some cases, the clock::v2 API may not be sufficient. In these cases, users can access the registers directly by calling Pac::steal to recover the PAC structs.

Implementations

impl Pac

pub unsafe fn steal(self) -> (Oscctrl, Osc32kctrl, Gclk, Mclk)

Escape hatch allowing to access low-level PAC structs

Consume the Pac and return the low-level PAC structs. This is useful when the clock::v2 API does not provide a necessary feature, or when dealing with the legacy clock::v1 API. For example, many of the clock::v1 functions require access to the Mclk peripheral.

Safety

Directly configuring clocks through the PAC API can invalidate the type-level guarantees of the clock module API.
