Chapter 7.Modes

The CPU board can be configured in User mode and Boot mode. User mode may be used to run and debug user code, while Boot mode

may only be used to program the Renesas microcontroller with program code via the SCI1 interface. Further details of programming the

flash are available in the SH7211 device hardware manual.

The CPU board provides the capability of changing between User and Boot / User Boot modes using a simple latch circuit. This

is only to provide a simple mode control on this board when the E10A debugger is not in use.

To manually enter boot mode, press and hold the SW1/BOOT. The mode pins are held in their boot states 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.

More information on the operating modes can be found in the device hardware manual.
