#78341 - RE: IAP commands for P89V51RD2
Responding to: ???'s previous message
Hi.

I had receive information from Philips.

There are two differents BITS. The datasheet don't say it !

SWR = software reset bit => FCF.1 (bit 1)

BSEL = bank select bit => FCF.0 (bit 0)

After REST, the SWR bit will be set. So, in order to use IAP routines, you must clear this bit.


Memory Map;

SWR=0 and BSEL =0
==> 0000H - 1FFFH (block 1) and above 1FFFh (block 0)
SWR=0 and BSEL =1
==> 0000H - FFFFH all block 0

Other combinations for SWR and BSEL , Philips didn't tell anything.
