The RSK supports Boot mode and Single chip mode.
Details of programming the FLASH memory is described in the R8C/25 Group Hardware Manual.
7.1. Boot mode
The boot mode settings for this RSK are shown in Table 7-1: Boot Mode pin settings below:
The software supplied with this RSK supports Boot mode using an E8a and HEW only. However, hardware exists to enter boot mode
manually, do not connect the E8a in this case. Press and hold the SW1/BOOT. The mode pin is held in its boot state while reset is pressed
and released. Release the boot button. The BOOT LED will be illuminated to indicate that the microcontroller is in boot mode.
When neither the E8a is connected nor the board is placed in boot mode as above, the Mode pin is pulled high by a 4.7k resistor.
When an E8a is used the Mode pin is controlled by the E8a.
7.2. Single chip mode
Because the Mode pin is pulled high, this RSK will always boot in Single Chip mode when the E8a is not connected and the boot switch is
not depressed. Refer to R8C/25 Group Hardware Manual for details of Single chip mode.
