25.8.2
USB boot mode executes programming/erasing of the user MAT by means of the control
command and program data transmitted from the externally connected host via the USB.
In USB boot mode, the tool for transmitting the control command and program data, and the
program data must be prepared in the host. The system configuration in USB boot mode is shown
in figure 25.9. Interrupts are ignored in USB boot mode. Configure the user system so that
interrupts do not occur.
