20.7
When the mode pins (MD0, MD1, and MD2) are set to on-board programming mode and the reset
start is executed, a transition is made to on-board programming mode in which the on-chip flash
memory can be programmed/erased. On-board programming mode has three operating modes:
SCI boot mode by PM2 setting, USB boot mode, and user program mode.
Table 20.5 shows the pin setting for each operating mode. For details on the state transition of
each operating mode for flash memory, see Figure 20.2.
Table 20.5 On-Board Programming Mode Setting
20.7.1
SCI 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 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 communication mode is set to asynchronous
mode. The system configuration in SCI boot mode is shown in figure 20.6. Interrupts are ignored
in SCI boot mode. Configure the user system so that interrupts do not occur.
