SPIs
Each SPI can be connected to an internally divided clock:
Table 10-6.
If the OCD trace system is enabled, the trace system will take control over a number of pins, irre-
spectively of the PIO configuration. Two different OCD trace pin mappings are possible,
depending on the configuration of the OCD AXS register. For details, see the AVR32 UC Tech-
nical Reference Manual.
Table 10-7.
The PDC and the peripheral modules communicate through a set of handshake signals. The fol-
lowing table defines the valid settings for the Peripheral Identifier (PID) in the PDC Peripheral
Select Register (PSR).
