//! @brief Interrupt priority
//!
//! This macro is made to be used with the \e am_hal_interrupt_priority_set()
//! function. It converts a priority number to the format used by the ARM
//! standard priority register, where only the top 3 bits are used.
//!
//! For example, AM_HAL_INTERRUPT_PRIORITY(1) yields a value of 0x20.
