25.8.1
SCI Boot mode executes programming/erasure of the user MAT or user boot MAT by means of
the control command and program data transmitted from the externally connected host via the on-
chip SCI_4.
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 communications mode is set to
asynchronous mode. The system configuration in boot mode is shown in figure 25.6. Interrupts are
ignored in SCI boot mode. Configure the user system so that interrupts do not occur.
