    Hi Larry,

    Are you referring to the TMS320BC52 device specifically. Or any device in the TMS320 family? TMS320BC52 is obsolete.

    TMS320 does not have on chip flash, so references to flash require use of the EMIF.

    Typically, the A0 address pin is only used in 8-bit mode. In 16-bit mode, the least significant address pin is A1 - 16-bit word addressable instead of byte addressable.

    The flash can have either an 8-bit or a 16-bit data bus, and the EMIF should be configured to match this bus width.

    Hope this helps,
    Mark
