22.2.1
MDCR is an 8-bit read-only register used to set this group operating mode and monitor the current
operating mode.
The EXPE bit is initialized in accordance with the mode pin states by a reset and in hardware
standby mode.
Bit 7—Expanded Mode Enable (EXPE): Sets expanded mode. In mode 1, EXPE is fixed at 1
and cannot be modified. In modes 2 and 3, EXPE has an initial value of 0 and can be read or
written.
