1. ELBC supports several modes of operation (chip select machines) - GPCM, FCM and UPM. MAchine is selected by ORn[MSEL] field. Please look P4080 Reference Manual, Section 13.1.3 for details.
2. ORn/BRn register pair for GPCM mode should be configured as described in Sections 13.3.5 and 13.3.6
3. CS line is configured by setting values to appropriate ORn/BRn register pair, where n is CS line number. For CS4 you should configure BR4/OR4.
4. GPCM has very small amount of configuration parameters, most of them are configured in ORn/BRn register pair. In addition you may look to eLBC_LBCR and eLBC_LCRR if necessary.
P4080 Reference Manual is available from P4080 product page, "Documentation" tab:
