The RSK supports Single chip mode and Boot mode.
When using the E8a debugger module supplied with the RSK the mode transitions are executed automatically. 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 E8a is not in use.
More information on the operating modes can be found in the M16C/29 Group Hardware Manual.
7.1.1.Boot mode
The boot mode settings for this RSK are shown in Table 7-1 below:
The software supplied with this RSK does not support Boot mode, except by using the E8a and HEW. 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 the E8a is not fitted the CNVSS pin is pulled low by a 100k resistor and the RP pin is pulled high by a 10k resistor, unless the board
is placed in boot mode as above, when they are actively driven. P1.6 is pulled up by 100k when the E8a is not fitted.
When an E8a is used these three pins are controlled by the E8a.
