5.3.3. SPI – S
P
ERIAL
ERIPHERAL
The SPI interface is not directly compatible with the SCI interface on the device. Selection of the connections to the SPI
interface should therefore be chosen to allow the operation of other peripherals as required.
5.3.4. CAN – C
ONTROLLER
The CAN device, when fitted, is permanently connected to microcontroller pins 56 & 57. Other options share these pins so be
sure that the alternate settings are made for the other peripheral options to avoid contentions on the board.
5.4. F

LASH
ROGRAMMING
The Flash Programming header is used with the Flash Debugging Module (FDM). The FDM is a USB based programming
tool for control and programming of Renesas microcontrollers, available separately from Renesas. This header provides
direct access for the FDM to control the EDK microcontroller.
To utilise this header the user must make the following changes to the board configuration.
1.
Select the FDM header using CJ4-C as marked on the silk screen. Please refer to section 5.2.
5.5. EXTERNAL DEBUG HEADER
The External debug header may be used with the Renesas E10T Debugger, Renesas LEM Debugger or a third party
debugger.
The E10T and LEM are on-chip debug emulators available separately from Renesas.
This header provides direct access for the debugger to control the EDK microcontroller.
5.6. B
C
OOT
ONTROL
The EDK provides a jumper selection to place the microcontroller device into boot mode. This jumper link grounds the NMI
pin on the device.
Always remove the power from the EDK before moving this jumper to prevent unintended effects in the processor that may
prevent the programming function from completing successfully.
