The normal boot function is described in
Serial boot is functionally identical to normal boot except that the SBoot bit in the SysCfg
register is set. This mode is available for a software configuration option that is readable by
the boot code.
In either normal boot or serial boot mode, once the processor starts up, it will begin to
execute the instruction at logical address 0x0000_0000. Various configuration options are
provided to select a memory device for booting from at address location 0. The options are
listed in
