3.21 J618 VDD_V3V3 Supply Control
Jumper J618 can be used to directly connect the VDD_3V3V
on-board main supply voltage with the external VCC voltage. In
normal operation the FET switch Q600A controls the VDD_3V3V
connection to VCC. Jumper J618 should remain open.
The following configurations are possible:
VDD_V3V3 Supply Control J618
VDD_V3V3 supply voltage is switched via
FET Q600A
open*
VDD_V3V3 supply voltage directly derived
from VCC
closed
* = Default setting

3.22 J619, J620 SPI Master/Slave Selection
Jumpers J619 and J620 are used to configure the SPI interface mode.
If both jumpers remain open, then both SPI interfaces operate in
Master mode. The SPI interfaces will operate in Slave mode if the
corresponding jumpers are closed.
The following configurations are possible:
SPI Master/Slave Mode Selection J619 J620
SPI0 operates in Master mode after RESET. open* -
SPI0 operates in Slave mode after RESET. closed
-
SPI1 operates in Master mode after RESET. - open*
SPI1 operates in Slave mode after RESET. - closed
* = Default setting
