Detailed Description

NVIC register definitions, IRQ numbers, and HAL interrupt control API for STM32F4.

This header provides:

• NVIC register mapping for the Cortex-M4 interrupt controller.
• Enumeration of all Cortex-M4 and STM32F4-specific IRQ numbers.
• HAL functions to enable/disable interrupts, set priorities, attach/detach callbacks, and query pending/active interrupt status.

The definitions are tailored for the STM32F4 series but are based on the ARM Cortex-M4 NVIC architecture. All register mappings match the reference manual.
