This RSK supports Boot mode and User mode.
Details of programming the FLASH memory is described in the H8/38347 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 port pin P24 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 port pin P24 is pulled high by a 100k resistor.
When an E8a is used the port pin P24 and P26 are controlled by the E8a.
7.2. User mode
Because the port pin P24 is pulled high, this RSK will always boot in User mode when the E8a is not connected and the boot switch is not
depressed. Refer to H8/38347 Group Hardware Manual for details of User mode. The user mode settings for this RSK are shown in Table
