After reset, the CPU fetches instructions from external memory and
executes them.
After reset, the CPU fetches instructions from internal boot ROM
and executes them. The boot ROM loads a user program into internal
RAM from USB, or via UART, and then branches to the internal
RAM. In this way the user program starts boot operation. Table 3.4.2
shows an outline of boot operation.
