C Interface
Jumpers J608, J609 and J610 are provided to connect the controller's
I
2
C interface to the on-board RTC and the phyCORE-connector. The
I
2
C signals SDA and SCL are available at pins X700C31 and
X700D32 if Jumpers J609 and J610 are closed. Jumper J608 connects
the RTC interrupt output to port P015. If all 3 jumpers remain open
the corresponding controller signals are available as standard I/O pins
at X700B47, X700A48 and X700B3.
The following configurations are possible:

3.18 J611, J612, J613, J614 SPI0 Interface
Jumpers J611 through J614 connect the SPI0 interface signals of the
microcontroller to the on-board SPI bus. The on-board
EEPROM (U607) is connected to the SPI bus. If the jumpers remain
open, then the applicable controller pins P04, P05, P06 and P10, can
be used with their alternative functions at phyCORE-connector pins
X700B48, X700A49, X700A50 and X700C13. The SPI interface
signals are available at X700C26, X700C28, X700D27 and X700D28.
The following configurations are possible:
