Table 12-13. PAR_SDRAM Field Descriptions
CS[3:2] pin primary function selection. The PAR_CSSDCS field configures each of the
CS[3:2] pins for one of its primary functions (either EIM chip select or SDRAMC chip select)
when the PAR_CS[3:2] bits are 1s. The PAR_CSSDCS values have no effect on the
CS[3:2] pin functions when the PAR_CS[3:2] bits are 0s. Refer to
Select Pin Assignment Register
SD_WE pin assignment. This bit configures the SD_WE pin for its primary function or
GPIO.
0 SD_WE pin configured for GPIO
1 SD_WE pin configured for SDRAMC WE function
SD_SCAS pin assignment. This bit configures the SD_SCAS pin for its primary function or
GPIO.
0 SD_SCAS pin configured for GPIO
1 SD_SCAS pin configured for SDRAMC CAS function
SD_SRAS pin assignment. This bit configures the SD_SRAS pin for its primary function or
GPIO.
0 SD_SRAS pin configured for GPIO
1 SD_SRAS pin configured for SDRAMC SRAS function
SD_CKE pin assignment. This bit configures the SD_CKE pin for its primary function or
