Flash Memory
The flash memory provide up to 4M x 8 bits of program storage that can
be loaded by the ADSP-2189M when it is programmed to boot from the
BMS (Boot Memory Select) and Mode A, B, C, and D switches. After the
ADSP-2189M processor is reset, the BDMA feature is used to load the
first 32 words of program memory from the byte memory space. Program
execution is held off until all 32 words are loaded. You can change the
mode of operation using the toggles on the mode DIP switch (SW3).
Refer to the ADSP-218x DSP Hardware Reference and data sheet for more
information on the processor’s boot modes.
