ST72264G datasheet

dear sir,

I have some doubt regarding ''ST72264G'' datasheet.I have found some ambiguity in the ''Memory Map''(page 10) section.In that doc Memory map is divided into 5 parts-

* HW Registers(0000h-007fh)

* RAM(0080-017fh)

* Reserved(0180h-Dfffh)

* Program Memory(E000h-Ffdfh)

* Interrupt & Reset Vectors(FFE0h-FFFFh)

In the same page u have showed program memory is divided into 2 parts:

sector 1(E000h-EFFFh)

sector 0(F000h-FFFFh) which is reserved for interrupt & reset vectors.

while Program Memory space itself is E000h-FFDFh,then how can be one of its part sector 0 which is in the space F000h-FFFFh is lying outside the program memory space.

While already you have showed Progarm Memory and Reset & Interrupt vector space as two distinct part in the memory map,then why did u combine it with sector 0 of progarm memory.

Pls exaplain.And rectify it in your ST72264G Doc.

Regards,

Arup

It does not impact the application anyway and it is same terminology which is used in all ST7 devices.
