3.2.2
Peripheral Functions
Each GPIO line can be assigned to one of several peripheral functions. The following table
describes how the various peripheral functions are selected. The last listed function has priority
in case multiple functions are enabled on the same pin.
3.2.3
Oscillator Pinout
The oscillators are not mapped to the normal GPIO functions and their muxings are controlled
by registers in the System Control Interface (SCIF). Please refer to the SCIF chapter for more
information about this.
3.2.4
JTAG port connections
If the JTAG is enabled, the JTAG will take control over a number of pins, irrespectively of the I/O
Controller configuration.
3.2.5
Nexus OCD AUX port connections
If the OCD trace system is enabled, the trace system will take control over a number of pins, irre-
spectively of the GPIO configuration. Three different OCD trace pin mappings are possible,
Table 3-2.
