| 5:0 | FSS1_CTRL0_S0_BOOT_SEG_PROXY | R/W | 0h | Selects the boot block to be used for the S0 (OSPI1) flash interface. If the s0_boot_size is 128 MB then only bits [4:0] of this field are used. Care must be taken to account for the address translation as to not fall off or wrap the address of the flash. (e.g. if both ECC and authentication are enabled for 64 MB boot, the highest valid block number is is 49, as sector 50 is only .2M Bytes in size.) Reset Source: mod_g_rst_n |
