18.5
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: user programming mode, user boot mode, and
boot mode.
For details on the pin setting for entering each mode, see table 18.1. For details on the state
transition of each mode for flash memory, see figure 18.2.
18.5.1
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 18.6. For details on the pin
setting in boot mode, see table 18.1. The NMI and other interrupts are ignored in boot mode.
Make sure the NMI and other interrupts do not occur in the user system.
SCI Interface Setting by Host: When boot mode is initiated, this LSI measures the low period of
asynchronous SCI-communication data (H'00), which is transmitted consecutively by the host.
The SCI transmit/receive format is set to 8-bit data, 1 stop bit, and no parity. This LSI calculates
the bit rate of transmission by the host by means of the measured low period and transmits the bit
