The Renesas Starter Kit supports Boot mode and Single chip mode.
Details of programming the FLASH memory is described in the M16C/26A Group Hardware Manual.
7.1. Boot mode
The boot mode settings for this Renesas Starter Kit are shown in Table 7-1: Boot Mode pin settings below:
The software supplied with this Renesas Starter Kit supports Boot mode using an E8a and High-performance Embedded Workshop only.
However, hardware exists to enter boot mode manually, do not connect the E8a in this case. Press and hold the SW1/BOOT. The mode
pins above 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.
When neither the E8a is connected nor the board is placed in boot mode as above, the P1_6 pin and RP/P8_5 pins are pulled high by 100k
resistors and the CNVSS is pulled low by a 100k resistor.
When an E8a is used these three pins are controlled by the E8a.
7.2. Single chip mode
As CNVSS is being pulled down by a 100k resistor, 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 M16C/26A Group Hardware Manual for details of Single chip mode.
