Setting the mode pins to mode 3 and resetting the hardware shifts the flash memory into boot
mode. In this mode, the embedded standard program is executed.
Boot mode executes programming/erasing of the user ROM, data flash, or user boot ROM by
means of the control command and program data transmitted from the externally connected host
via the on-chip SCI_1.
In 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 boot mode is shown in figure 23.9. Interrupts are ignored in boot
mode. Configure the user system so that interrupts do not occur.
