Section 3 MCU Operating Modes
3.1.2
This LSI have a mode control register (MDCR) that indicates the inputs at the mode pins (MD1
and MD0), a system control register (SYSCR) and bus control register (BCR) that control the
operation of the MCU, and a serial/timer control register (STCR) that controls the operation of the
supporting modules. Table 3.2 summarizes these registers.

3.2.1
MDCR is an 8-bit read-only register that indicates the operating mode setting and the current
operating mode of the MCU.
The EXPE bit is initialized in coordination with the mode pin states by a reset and in hardware
standby mode.
