The following explains the SRAM Write operation accomplished through a table(s) of up to four devices with the following
parameters ( TLSZ = 01). The hardware diagram for this table is shown in Figure 12-7. The following assumes that SRAM access
is achieved through CYNSE70256 device number 0. Figure 12-8 and Figure 12-9 show the timing diagram for device number 0
and device number 3, respectively.
