DSP EXTERNAL MEMORY INTERFACE
MA[14:0]
External Memory Address
Address lines for the external SRAM devices. The external memory interface can be used for
DSP code space if the EXT_SRAM_EN (in HDCFG, bit 5) is set. Otherwise, the DSP will use
internal ROM as the code source.
MD[15:0]
External Memory Data Bus
Word wide data bus for the external SRAM. Use 6ns memory for maximum DSP performance.
MCS#
External Memory Chip Select
Chip select line for the external SRAM devices.
MWE#
External Memory Read/Write Control
Selects the external SRAM for reading or writing.
