Configuration
The ConnectCore 9M 2443 Module supports 8 configuration pins:
4 pins provided for software configuration, which are routed to standard pin
locations on the development board (CONF[7:4]).

4 pins provided for hardware configuration, routed to the base board at
standard pin locations, including debug enable (DEBUG_EN#) and NAND flash
write protect (NAND_FWP#).

Power Supply
The common power supply for the module is 3.3VDC. VLIO has to be connected to
3.3V on the base board.
3.3V on the base board.
The CPU specific core voltage of 1.2V@300MHz (1.3V@400MHz) and the voltage for
VDD alive will be generated on the module from the VLIO input, while the voltage for
memory power supply and I/OS is fed directly from the 3.3V.

The following requirements have to be met by the power supply:
The voltage at pin RTCVDD has been connected to 3.3V, even though the RTC is not
used. If VDD_RTC is not used, it has to be high (VDD_RTC=3.3V).

The S3C2443 supports DVS (dynamic voltage scaling). This means that the core
voltage may be reduced to 1V in idle mode while clock frequency is also reduced.

If a battery supplies the power for the module, the pin BATT_FLT# can be connected
to a comparator output on the base board. The comparator may supervise the battery
