BSL mode constraint

Hello,

Micon used - ST10f280
Mode of operation - BSL

Question 1->
In user manual for ST10F280, it is written "While operating in BSL mode accesses to internal Flash is partly redirected".

Is it talking about Flash Write only?
Will I be able to write into Flash while being in BSL mode?

Question 2->
I think we can't use interrupt during BSL mode. Will anyone give me any comment on this?

Thanks
Rashmi

    "Accesses to internal flash are partly redirected" means that it is not possible to execute code from internal flash in BSL mode. You can read from and write to it, however. The fact that the ST10 Flasher program works clearly indicates that it's possible:

    Why not? I think you can.
