33 / 382 page  DS13543 Rev 1 33/382 STM32U5Axxx Functional overview 99 The boot address option bytes allow any boot memory address to be programmed. However, the allowed address space depends on the flash memory RDP level. If the programmed boot memory address is out of the allowed memory mapped area when RDP level is 0.5 or more, the default boot address is forced either in secure flash memory or nonsecure flash memory, depending on TrustZone security option as described in the table below. Table 7. Boot modes when TrustZone is enabled (TZEN = 1) BOOT_ LOCK nBOOT0 FLASH_ OPTR[27] BOOT0 pin PH3 nSWBOOT0 FLASH_ OPTR[26] RSS com- mand Boot address option-byte selection Boot area ST programmed default value 0 -0 1 0 SECBOOTADD0 [24:0] Secure boot address defined by user option bytes SECBOOTADD0[24:0] Flash: 0x0C00 0000 -1 1 0 N/A RSS RSS: 0x0FF8 0000 1- 0 0 SECBOOTADD0 [24:0] Secure boot address defined by user option bytes SECBOOTADD0[24:0] Flash: 0x0C00 0000 0- 0 0 N/A RSS RSS: 0x0FF8 0000 -- - ≠0N/A RSS RSS: 0x0FF8 0000 1- - - - SECBOOTADD0 [24:0] Secure boot address defined by user option bytes SECBOOTADD0[24:0] Flash: 0x0C00 0000 Table 8.
