Boot Mode and Single chip mode. This circuit is not required on customers’ boards as it is intended for providing easy evaluation of the operating modes of the device on the Renesas Starter Kit. Please refer to the hardware manual for more information on the requirements of the reset circuit. -
Page 16: Lin Interface
6.9. LIN Interface This Renesas Starter Kit has hardware LIN interface. The interface is available on connector ‘LIN’. The connector ‘J5’ functions as power connector for LIN. The device can be operated either in ‘Master’ mode or ‘Slave’ mode. The device performs LIN communication in cooperation with Timer RA and UART0. -
Page 17: Chapter 7. Modes
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/2C Group, R8C/2D Group Hardware Manual for details of Single chip mode. -
Page 18: Chapter 8. Programming Methods
Chapter 8. Programming Methods The board is intended for use with High-performance Embedded Workshop and the supplied E8a debugger. Refer to R8C/2C Group, R8C/2D Group Hardware Manual for details of programming the microcontroller without using these tools. -
