Table 12: Differences in Pinning and Pad Cells – SPI
If a Quad SPI flash is used for fast start up at netX 50 the already published workaround via the
communication controller is working also with netX 51.
In addition the netx 51 includes a very fast Quad SPI controller which also support “execution in
place” to run program code directly out of the Quad SPI flash. This option can be used only if a
new PCB is designed because the signal MEM_A18 is used as SPI_SIO2 and MEM_A19 as
SPI_SIO3.
The schematic shows an example how to set up the configuration of the Host Interface by the
strapping options and how to connect a Quad SPI flash.
