External Bus Interface

The MODM7AE70 provides 17 address lines (A0-A16) and a 16-bit data bus line (D0-D15). The data and address lines shared with the SDRAM are buffered to the module's P1 header pins. Please refer to the schematic show below [TODO: Add this]. Please refer to SAME70 datasheet, sections 33 on External Bus Interface (EBI) and section 34 on Static Memory Controller (SMC), for details on peripheral functionality and configuration.
