JP13 - IOVDD Source
JP13 is used to select the source for the IOVDD supply voltage.
When the jumper is at position 1-2, the IOVDD voltage must be provided to pin 7 on the H9 connector.
When the jumper is at position 2-3, the IOVDD voltage is provided by the 3.3V power supply of the board.

JP16 - SDRAM Width Select
JP16 is used to select the bus width of the external SDRAM.
When the jumper is at position 1-2, the external SDRAM is 32 bits wide and the memory size is 32M bytes. In this
configuration, the memory consists of 2 chips in parallel, each16M bytes and 16 bits wide.
When the jumper is at position 2-3, the external SDRAM is 16 bits wide and the memory size is 16M bytes. In this
configuration, one memory chip is disabled and only one chip is active (16M bytes and 16 bits wide).
