Section 3 MCU Operating Modes
3.1 Selection of Operating Modes
This LSI has four operating modes and four clock modes. The operating mode is determined by
the setting of MD3–MD0, and FWP pins. Do not change these pins during LSI operation (while
power is on). Do not set these pins in the other way than the combination shown in Table 3.1.

Notes: The symbol x means “Don’t care.”
1. The mode3 and an 8-bit space of MCU extension mode is supported.
2. Programming mode for flash memory. Supported in only F-ZTAT version.
3. Cannot be used for this LSI.
There are two modes as the MCU operating modes: MCU extension mode and single chip mode.
There are two modes to program the flash memory (on-board programming mode): boot mode and
user programming mode.
