XMC_EBU_BUS_READ_CONFIG_t Struct Reference

#include <xmc_ebu.h>

Detailed Description

Read configuration for a region of EBU

The structure presents a convenient way to set/obtain the read and read timing configuration for a region for EBU. The XMC_EBU_ConfigureRegion() can be used to populate the structure with the read configuration values for EBU.
