General purpose ADC connector
Eight analog input lines are available on J27 connector. Inside the connector it is also
possible to determine the range of the conversion by setting the conversion limits on the pin
J27-19 (lower limit) and J27-1 (upper limit) via jumpers.
By default the on-board VREFP and VREFN jumper configuration of ADC is selected as
shown in Table 15.
The following relationship between the pins should be guaranteed in the application:

NOR Flash
The NOR Flash is connected to the EMI interface of CPU, two NOR Flash (U7,U10) are
available on the board, the bit-width is 32-bit, the current memory size is 128Mbit. The 32bit
NOR Flash is mapped to memory space of CPU, use Jumpers (JP1,JP2,JP3,JP4,JP5,JP6)
to select one of six memory space.
By default the memory space mapping of NOR Flash is selected as shown in Table 16
Table 15.
