14.4
When the pin is set in on-board programming mode and the reset start is executed, the on-board
programming state that can program/erase the on-chip flash memory is entered. On-board
programming mode has three operating modes: boot mode, user program mode, and user boot
mode.
For details of the pin setting for entering each mode, see table 14.6. For details of the state
transition of each mode for flash memory, see figure 14.2.
Table 14.6 Setting On-Board Programming Mode
14.4.1
Boot mode executes programming/erasing user MAT and user boot MAT by means of the control
command and program data transmitted from the host using the on-chip SCI. The tool for
transmitting the control command and program data must be prepared in the host. The SCI
communication mode is set to asynchronous mode. When reset start is executed after this LSI’s
pin is set in boot mode, the boot program in the microcomputer is initiated. After the SCI bit rate
is automatically adjusted, the communication with the host is executed by means of the control
command method.
The system configuration diagram in boot mode is shown in figure 14.6. For details on the pin
setting in boot mode, see table 14.6. The NMI and other interrupts are ignored in boot mode.
However, the NMI and other interrupts should be disabled in the user system.
