† The following parameters are programmable via the EMIF CE Space Secondary Control register (CExSEC):

− Read latency (SYNCRL): 0-, 1-, 2-, or 3-cycle read latency

− Write latency (SYNCWL): 0-, 1-, 2-, or 3-cycle write latency

− CEx assertion length (CEEXT): For standard SBSRAM or ZBT SRAM interface, CEx goes inactive after the final command has been issued

(CEEXT = 0). For synchronous FIFO interface with glue, CEx is active when SOE is active (CEEXT = 1).

− Function of SADS/SRE (RENEN): For standard SBSRAM or ZBT SRAM interface, SADS/SRE acts as SADS with deselect cycles

(RENEN = 0). For FIFO interface, SADS/SRE acts as SRE with NO deselect cycles (RENEN = 1).

− Synchronization clock (SNCCLK): Synchronized to ECLKOUT1 or ECLKOUT2
