The Renesas Starter Kit supports Boot mode and Single chip mode.
Details of programming the FLASH memory is described in the R8C/23 Group Hardware Manual.
7.1. Boot mode
The Boot mode settings for this Renesas Starter Kit are shown in Table 7-1: Boot Mode pin settings below:
The software supplied with this Renesas Starter Kit supports Boot mode using an E8a and High-performance Embedded 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 Renesas Starter Kit will always boot in Single chip mode when the E8a is not connected and the
boot switch is not depressed. Refer to R8C/23 Group Hardware Manual for details of Single chip mode.
