Detailed Description

Hardware Abstraction Layer for synchronous SPI Master mode communication.

This file defines the API for interacting with an SPI bus in master mode. It provides functions for initialization, configuration, reading, writing, and combined operations using synchronous blocking transfers.

Synchronous mode provides blocking operations with automatic transfer optimization. The HAL automatically selects the best transfer method (CPU vs DMA) based on transfer size and hardware capabilities - applications don't need to know. All operations block until completion or timeout.

Note

For non-blocking asynchronous operations, see nhal_spi_master_async.h
