Table 6.
1. Write operations or with ROMS1=’1’ or bootstrap mode
The table above refers to the configuration when bit ROMS1 of SYSCON register is set.
When Bootstrap mode is entered:
●
●
●
●
In Bootstrap mode, by default ROMS1 = 0, so the first 32 KBytes of IFlash are mapped in
segment 0.
Example:
In default configuration, to program address 0, user must put the value 01'0000h in the
FARL and FARH registers, but to verify the content of the address 0 a read to 00'0000h must
be performed.

Test-Flash is seen and available for code fetches (address 00’0000h)
User I-Flash is only available for read and write accesses
Write accesses must be made with addresses starting in segment 1 from 01'0000h,
whatever ROMS1 bit in SYSCON value
Read accesses are made in segment 0 or in segment 1 depending of ROMS1 value.
