I am developing a control board using ADSP-21489. I need a large size external RAM (SDRAM or SRAM) and 10-Cha PWM Outputs at the same time. Can I configure the external port to make 10 ADDR lines for PWM outputs and other 14 ADDR lines for interfacing external RAM (8-bit address packing)? If yes, can I still use 32MByte SRAM or 256MByte SDRAM?
Thanks in advance.
