• Manufacturer: Renesas Electronics Corporation.

3.1
This LSI has four MCU operating modes and three on-chip flash memory programming modes.
The operating mode is determined by the setting of FWE, MD1, and MD0 pins. Table 3.1 shows
the allowable combinations of these pin settings; do not set these pins in the other way than the
shown combinations.
When power is applied to the system, be sure to conduct power-on reset.
The MCU operating mode can be selected from MCU extension modes 0 and 2 and single chip
mode. For the on-chip flash memory programming mode, boot mode, user boot mode, and user
program mode which are on-chip programming modes are available.
