Function Documentation

◆ CSL_emifGetRevision()

uint32_t CSL_emifGetRevision ( CSL_emif_sscfgRegs *  pEmifSsRegs)

Return revision of the EMIF subsystem module.

This function returns the contents of the EMIF subsystem revision register. Consult the EMIF subsystem module documentation for a description of the contents of the revision register.

Parameters
pEmifSsRegs[IN] Pointer to the EMIF Subsystem register space base.
Returns
The 32-bit revision register is returned.
