If the desired method to receive an interrupt is based on the completion of a certain number of commands, the following settings must be performed:
On CCC event configuration , the CCC feature should be disabled (that is, SATA_CCC_CTL[0] EN should be kept at 0b0).
Due to the single SATA controller HBA port integration, the source of the CCC interrupt, if enabled, is always HBA port 0. On a CCC interrupt, the SATA_CCC_CTL [7:3]INT read-only bit changes to 0x0 (its reset value is 0x1) . As a consequence, the STA_IS[0] IPS bit is set to 0x1.
