38. SPI Components

38.1. Reference

• For component documentation, refer to spi_component

38.2. Notes

• CS signals in master examples are GPIO-emulated for flexible transaction control

• To enable hardware CS control in master examples, invoke spi_master_enable_cs_select API during initialization or pre-transaction

• spi_master_enable_cs_select availability depends on HPM_IP_FEATURE_SPI_CS_SELECT macro definition in SOC’s hpm_soc_ip_feature.h
