Detailed Description

Defines the API for low-level I2C bus transfers in a Hardware Abstraction Layer (HAL).

This header declares an API function for low-level I2C bus transfers, referencing structures and enums defined in nhal_i2c_types.h to facilitate complex I2C transactions, including multi-message transfers with explicit control over START/STOP conditions and addressing.
