Synchronous burst write
Table 2-16 and Table 2-17 list the smc_opmode0_<0-3> and SRAM Register settings.
Figure 2-21 shows a synchronous burst write transfer that is delayed by the smc_wait_0
signal. You must configure the memory to assert smc_wait_0 one cycle early and with
an active LOW priority. The smc_wait_0 signal is again registered with the fed back
clock and smc_mclk0 before being used. The smc_wait_0 signal is used in the
smc_mclk0 domain to the memory interface FSM.
