44 / 346 page  Obsolete Product(s) - Obsolete Product(s) Internal Flash memory ST10F296E 44/346 Table 9 refers to the configuration when bit ROMS1 of the SYSCON register is set. When bootstrap mode is entered: ● Test-Flash is seen and is available for code fetches (address 00’0000h) ● User IFlash is only available for read and write access ● Write access must be made using addresses in segment 1 that start at 01'0000h, irrespective of the ROMS1 bit value in the SYSCON register. Note that the user must not rely on the ROMS1 bit because it is ‘don't care’ for write operations. ● Read access is made in segment 0 or in segment 1 depending on the ROMS1 value. In bootstrap mode, ROMS1 = 0 by default, so the first 32 Kbytes of IFlash are mapped in segment 0. Example To program address 0 using the default configuration, the user must put the value 01'0000h in the FARL and FARH registers. However, to verify the content of address 0 a read to 00'0000h must be performed. Table 9.
