DPI Interface

The digital peripheral interface (DPI) pins are connected to a second sig-
nal routing unit of the processor (
is a flexible routing system, providing a large system of signal flows within
the processor. In general, the
internal peripherals in various combinations.
The DPI pins are connected to the SPI flash memory, SPI of the
AD1835A codec, a UART, a 20-pin header, and five LEDs.

To use the DPI for a different purpose, disable any signal driving a DPI
pin with a switch (see
DPI pin connected to a LED can be used without having to disconnect
the pin. You can, however, see the respective LED turn
