Specifications of R0K564112S000BE#WS

• Contents: CPU Board, LCD Display Module, E8 Emulator, Cable, QuickStart Guide and CD-ROM
• For Use With/related Products: R32C/111
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The MCU 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 MCU with program code via the serial interface. Further details of programming the flash are available in the
R32C/111 device hardware manual.
The RSK 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 E8A 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.
