I am using spansion S29GL128P flash (16 MByte). This flash can be connected in both byte and word mode.

Since i am using this flash also for booting i am compelled to connect in byte mode and connected to MS1

I have connected all the 24 address lines from DSP to flash.

Now reading from any addresses below 0x4800000 is not a problem with or without PKDIS enabled.

Now  to read from any address above 0x4800000, i need to enable PKDIS and this reading is not possible with PKDIS disabled.

Am i correct regarding this read procedure?
