22.9
SCI boot mode executes programming/erasing of the user ROM by means of the control command
and program data transmitted from the externally connected host via the on-chip SCI_1.
In SCI boot mode, the tool for transmitting the control command and program data, and the
program data must be prepared in the host. The serial communication mode is set to asynchronous
mode. The system configuration in SCI boot mode is shown in figure 22.7. Interrupts are ignored
in SCI boot mode. Configure the user system so that interrupts do not occur.
