10. External SRAM Connection
It can be used by the ability of able to connect external SRAM to processing of data tables, such as
coefficient data, or data delay.
The function of the terminal for external SRAM control is shown in Table 7. Moreover, the example of
connection of external SRAM is shown in Figure 21.
