3.1.1 Basic Configuration
This section explains the basic configuration.
Basic Configuration of FLASH MCU Programmer (Clock Asynchronous Serial Write)
FLASH MCU Programmer writes data, through clock asynchronous serial communication, to built-in flash memory of a
microcontroller installed in the user system when the PC and the user system are connected through RS-232C cable.
In these series, serial programming (UART communication mode) is possible by any clock, crystal
oscillator or external
clock or built-in High-speed CR oscillator.
If flash erase is executed to the flash memory that its flash security is enabled when built-in CR oscillator is used instead
of external crystal oscillator, serial communication will be disconnected after the erase operation and then CR trimming
data will be lost. When flash security is enabled, use external crystal oscillator.
Figure 3-1 shows the basic configuration of FLASH MCU Programmer, and Table 3-1 lists the system configuration.
