Section 3 MCU Operating Modes
3.2
The following registers are related to the operating mode setting.
• Mode control register (MDCR)
• System control register (SYSCR)
3.2.1
MDCR indicates the current operating mode. When MDCR is read from, the states of signals
MD2 to MD0 are latched. This latch is canceled by a reset.

Reserved
These are read-only bits and cannot be modified.
Mode Select 3 to 0
These bits indicate the operating mode selected by
the mode pins (MD2 to MD0) (see table 3.2).
When MDCR is read, the signal levels input on pins
MD2 to MD0 are latched into these bits. These
latches are released by a reset.
