Nested Vector Interrupt Controller

Implementations§

Disables interrupt

Enables interrupt

This function is unsafe because it can break mask-based critical sections

Returns the NVIC priority of interrupt

NOTE NVIC encodes priority in the highest bits of a byte so values like 1 and 2 map to the same priority. Also for NVIC priorities, a lower value (e.g. 16) has higher priority (urgency) than a larger value (e.g. 32).

Checks if interrupt is enabled

Checks if interrupt is pending

Forces interrupt into pending state

Sets the “priority” of interrupt to prio

NOTE See get_priority method for an explanation of how NVIC priorities work.

On ARMv6-M, updating an interrupt priority requires a read-modify-write operation. On ARMv7-M, the operation is performed in a single atomic write operation.

Unsafety

Changing priority levels can break priority-based critical sections (see register::basepri) and compromise memory safety.

Clears interrupt’s pending state

Pointer to the register block

👎Deprecated since 0.7.5: Use the associated constant PTR instead

Returns a pointer to the register block
