3.1
This LSI has four operating modes and four clock modes. The operating mode is determined by
the setting of MD3 to MD0, and FWP pins. Do not set these pins in the other way than the
combination shown in table 3.1. When power is applied to the system, be sure to conduct power-
on reset.

Notes: 1. MD3 and MD2 pins are used to select clock mode.
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.
